16 Using a Buck boost converter

17 Using a Buck boost converter Engine running detection The converter has a unique engine running detection in order to be able to detect a running vehicle engine. This prevents the converter from charging the starter battery if the alternator does not supply power. The converter is switched on: When the engine is running and the supply voltage is >= (adjustable) volts and any (adjustable) minute blocking is over. Pin 1 input (as an alternative to the engine running detection) The converter may also be switched on with a switch or relay contact. Switch on: The converter is switched on: If pin 1 input >= 2 volts, and the supply voltage is >= (adjustable) volts and any blocking is over.

42 Principle of Victron Energy charger/inverters

43 Overload of inverters Whats happening when the overload LED is On or blinking?

44 Overload of inverters Either a too high inverter current or a too low inverter output voltage.

45 Overload of inverters Overload can take place when the the state is : Invert or PowerAssist When the overload LED is lit up during charging, contact service! Always first there is the: pre-alarm Alarm Switch off

46 Overload of inverters Normally when a Multi switches off, it stays off for 30 seconds and will then automatically restart again. These 30 seconds are fixed. So when you encounter a situation in which the off time is unequal to 30 seconds it will most likely not be a firmware issue. (most likely it will be for instance hardware which switches the device or it can be a remote panel/assistant which decides to switch off.)

47 Overload of inverters At an overload the Multi tries to restart 3 times If the Multi is switched of within 30 sec after a restart again it will will go into lock (permantent OFF ) and needs to be restarted by switching off/on If the unit runs for longer the 30sec the timer is cleared again.

48 Overload of inverters While in the off or permanent off state the LED indication is in the remember state. All errors which occur will get displayed. No indication is cleared. In other words, the error LED indication can get worse and cannot get better

49 Overload of inverters Short circuit / excessive overload protection The multi s do have a protection mechanism for the powerpack. When it discovers that the current limitation for the FET s is constantly activated it will turn off the multi permanent with an overload indication. If this multi is in a VEBus system then the whole system will turn off. In a multi phase system the leaders of the other phases will display VEBusError code 1 (float LED blinks in opposite phase with the Inverter LED) during the first 30 seconds. After that they will start indicating OK codes

50 Overload of inverters What can inverters handle? 1 Max power (output voltage less then normal ) 30 cycles 2 Max power (output voltage is normal ) 2 minutes 3 30% overload 30 minutes* *This depends on ambient temperature.

51 Overload of inverters Single phase motor draw approx. 6 x Inom during start-up Three phase motor draw approx. 3 x Inom during start-up Inductive loads / Capacitive loads inverter size needs + 100%* (*) Power factor approx. 0.7

52 MK3-USB No new functionalities for normal use (VEFlash, VEConfig, etc) But an enabler for low cost monitoring on for example RaspberryPIs and similar low cost computers. Minimal cost to monitor a Multi: RaspberryPi 20 EUR MK3-USB Total: 70 EUR C ex VAT 90 EUR ex VAT

54 Off grid systems

55 A typical system The Multi connects to batteries. The Multi powers loads, such as lights, TVs or and/or refrigerators. These are the AC loads. The Multi can be powered by grid, generator and/or AC Solar. This is the AC input. The Multi can be powered via the batteries by DC solar, alternators and/or DC generator. This is the DC input. There also might be loads in the system that connect to the battery, like a water pump. This is the DC load.

56 System calculations Important questions: What is the total use in KWh? What battery capacity is needed? How long stand alone time? What charge current is needed? Quiet energy and/or generator?

57 Perform the calculations in this order Step 1. Power out calculations: How big are the loads At which times Step 2. Inverter calculations: Peak power requirements Step 3. Power in calculations: Which source(s) At which times during a day Ste 4. Battery calculations: Autonomy Depth of discharge Charge rate Discharge rate

58 Watt When making system calculations, always calculate in energy In other words, always calculate in Watts. Watt = Volt x Amp kw = kilo Watt = 1000 W kwh = kilo Watts per hour

59 On-grid or off-grid? Self consumption systems cater for the average load in a system Off-grid systems have to cater for the peak load in the system Because off grid systems have to cater for peak loads they generally speaking contain twice the inverter size and twice the battery bank size. Off grid systems containing PV have to be calculated for winter time and have to be able to potentially be able to deal with a number of days of bad weather.

61 Charge/discharge current Current vs Capacity for a Lithium battery C C ,5C Installed Ah

62 Batteries and off-grid PV Issues with lead-acid batteries in off-grid PV: Round trip energy efficiency not impressive Regular full recharge needed Dramatically shortened service life if used in permanent deficit mode Would Li-ion be a better alternative in some applications? Expensive (but over 2000 cycles at 80% DoD) Battery management system needed to balance cells and to prevent over-discharge Excellent round trip energy efficiency No full recharge needed Will not deteriorate if used in permanent deficit mode (unless discharged beyond a well defined minimum cell voltage)

63 Solar systems Off-grid and backup

64 Off grid or backup systems These are systems that do not feed back into the grid This applies to these systems: Without grid With very bad or unreliable grid Backup Peak shaving No ESS!

65 Backup systems

66 Back up systems These are systems where grid or generator is not always available or frequently fails A battery is used to power loads when mains is not available The focus is on the battery, Ideally the battery is always full unless there is a blackout The battery should never be let to go empty, so it needs to be recharged from solar or from a backup generator If the power is restored the battery will need to be charged up as fast as possible

67 Basic Multi backup system Should the grid or generator fail the Multi will run off the batteries When the batteries get low the Multi will turn off and will stop powering he AC loads When the grid or generator is back the Multi will charge the batteries again and will power the AC loads

68 Backup system with solar Solar can be added to a backup system But always keep the focus on the state of charge of the battery. Keep the battery full where possible Don t turn a backup system into an energy storage system Ideally use DC solar because this is easier to manage during a blackout than ac solar is

69 Double backup system using a Filax When the generator or grid has failed the first Multi will provide AC power to the load Should the first Multi fail the Filax will seamlessly switch over to the second Multi The Multis can connect to either the same or to individual battery banks

70 Bypass / redunancy In this system isolator switches are used These provide a way to isolate a unit for maintenance or replacement without losing power to the AC loads

71 Hybrid system Combining generator with inverters These systems combine generators with Multis or Quattros They provide backup power Reduced fuel consumption emissions The generator will run in its optimal operational zone The generator size can be reduced

72 Bredenoord E-saver

73 Peak shaving To supplement limited grid or generator power supply It makes use of the power assist feature of the Multi Can be set up with the AC input current setting in VE.Configure

74 Intentional islanding To prioritize solar energy over grid energy Also used in areas with a bad grid and/or brown outs and spikes. System runs in Inverter mode, even when the public grid is available. Can be easily set up with the AC Ignore setting in VE.Configure Grid Loads Grid Loads Grid Loads Grid Loads Grid Loads Battery is full Grid is ignored solar energy is used battery is charged Battery is full enough Grid is still ignored Battery energy is used Battery is discharged Battery is empty Grid is let in Grid energy is used Battery is charged Battery partly recharged Grid is ignored again Battery energy is used Battery is discharged Batteries are full Grid is ignored Solar energy is used Battery is charged

75 AC ignore, using the grid as a backup generator The Multi disconnects from the grid as long as the batteries are full enough It can, for example, let grid in when the batteries are low or when the AC load is above a certain value It can even drive its the AC input relay based on a signal from the relay in the BMV or in the CCGX Can be set up with the AC Ignore setting or Assistants in VE.Configure

76 Off grid systems

77 An off-grid system No mains available Often a generator available Usually solar available

78 Small solar system Examples Security camera systems Electronic Traffic signs And so on

79 Streetlight systems Our MPPTs have day/night sensing Programable load output LED driver control through VE direct port (PWM signal) via special cable

80 Larger DC off-grid system

81 Small inverter DC off-grid system

82 Large inverter/charger DC off-grid system

83 The EasySolar - Complete system in one enclosure

84 Multiple MPPTs can be used

85 Large DC solar system

86 What type of PV is going to be used? AC-Coupled system Uses PV inverters DC-Coupled system uses MPPT solar charge controllers Or a combination of the two?

87 AC versus DC AC PV Pros: Less and thinner AC cabling PV array can be far away from the installation Cons: 1.0 rule Programming needed System will not recover from low battery if there is no backup generator DC PVos: Better for charging batteries More efficient if most energy needs to be stored Easy to setup. Default products can be used, no programming needed Failsafe in case batteries are too far discharged Cons: Not so suitable for very large arrays (max voltage 250V) Not suitable for boats or vehicles

88 Off-grid AC solar Consider Add a proportion DC Solar What will happen when batteries are empty?

94 Battery choice Full Cycle life Full Discharge Lithium Lead acid

95 Default unit By far the easiest option The requirements DC solar or no solar No feed-back into the grid possible

96 When to use Off grid DC solar systems Automotive or marine systems Back up systems Reducing generator running time Peak shaving systems (using the power assist feature)

97 AC input current limit

98 Power control current limit The Multi needs to know how much current it is allowed to take from grid or generator You need to set the current limit with the Multi Control panel, CCGX or via the VE.Configure software!

99 Virtual switch ignore AC

100 Ignore AC input Easy to set up, via virtual switch, no firmware upgrade needed The requirements DC solar No feed-back into the grid possible When to use Unreliable grid, with frequent blackouts or brownouts

101 Ignore AC The AC input relay is driven by battery, load or AUX input conditions

102 Virtual switch AC - ignore In this example grid will be let in: As soon as the battery voltage drops below 23.5 V for 60 seconds or the SOC is lower than 50%

103 A note on SOC The build in battery monitor in the Multi is not very accurate in systems with DC inputs (solar) or DC loads. In these systems consider using a BMV together with a CCGX. The CCGX can copy the BMV SOC to the Multi

104 Virtual switch - frequency shift

105 Virtual switch - frequency shift To turn off an PV inverter via a frequency shift once the batteries are full. Requirements AC coupled inverter capable of turning on or off based on frequency shift No grid feed

106 Virtual switch The settings can be found in the VS options tab of the virtual switch tab No firmware update needed This is possible in a default unit

107 Important considerations The 1.0 rule: do not install more KW solar than the KW rating of the Multi or Quattro Check if the PV inverter used is capable of turning on or off based on frequency shift This Assistant prevents overcharging of a battery by turning the PV inverter off. But be aware that if this system is set up incorrectly battery overcharge will occur Consider using the PV inverter Assistant instead

108 Before using an Assistant

109 Where to find? To find assistant info: See the manual sections of the Multi and Quattro product pages. Or see VE.Configure Don t forget that you can run a demo version of VE.Configure Assistants are only available when upgrading to 4 version firmware Firmware is available from our professional website. See: Note: In the past a password was needed (Watson) but is not needed anymore

110 Firmware Our firmware version number exists of three parts. For example : 26 is the microprocessor family group (19 is the old microprocessor) 41 is the model for example Quattro 24/ is the firmware type (1=default firmware 4=assistant firmware) 43 is the firmware version

111 Firmware available from Victron professional Let Victron professional add all our firmware files to your dropbox. An Apps folder will be created in your Dropbox. This folder will always stay up to date Or Download the required file from Victron professional How to update firmware see:

112 Stay up to date Always make sure you use the most up to date assistant and firmware We improve functionality all the time See changelogs in the VE.Bus firmware folder:

113 PV inverter Assistant

114 PV inverter Assistant This Assistant prevents overcharging of a battery by turning the PV inverter off

115 Frequencies This Assistant prevents overcharging of a battery by turning the PV inverter off Check it the PV inverter can switch on or off based on a frequency shift Be aware that battery overcharge will occur if this system is set up incorrectly

116 The 1.0 rule The Factor 1:0 rule: Do not install more KW solar than the KW rating of the Multi or Quattro The 1.o rule

117 AC current sensor assistant

118 Safety switch assistant

119 Safety switch Use to switch off the AC output when an external switch is pressed This assistant might conflict with lithium assistants

120 Relay assistant

121 Relay assistant Use to drive one of these relays: The programmable relay The K relays Solar box relays (obsolete) AC output 2 Via the general flag: AC input 1 AC input 2 AES mode

122 Switch conditions and time Conditions and for how long: AC load DC voltage Charge state Fan LED alarm AC input Signal on AUX or Temp connector SOC

123 Notes Two assistants needed: You will always need two assistants, one to drive the relay on and the other to drive the relay off Usage examples: Driving an extraction fan once the fan in the Multi has turned on Turn on AC output 2 when the batteries are full to run a dump load Turn off AC output 2 when the batteries are full to turn off a PV inverter connected to that output

124 General flag

125 General flag The General flag can be set or cleared by other assistant, like the Generator assistant and the relay assistant. The general flag will then preform the action chosen in this assistant. Example: The generator assistant activates the software flag Once the software flag is activated AC input 1 is ignored

126 Generator start and stop Assistant

127 Generators Generators can be used with our products without problems The generator can be remote started from the: CCGX BMV Multi or Quattro.

128 Generator start using a CCGX - Preferred option See:

129 Generator start using a BMV

130 Generator start using a Multi or Quattro Via VE.Configure - virtual switch or Via VE.Configure Generator start/stop Assistant

131 Generator start and stop Assistant This assistant is used for starting a generator in off grid systems. Consider using the CCGX generator start instead But it can also be used for: Selectively letting grid in. To turn on a dump load once the batteries are full To turn of a grid feed inverter connected to output 2 of a Quattro To drive a contactor to turn a grid feed inverter off

132 Generator starting This assistant helps you to setup a programmable relay for starting and stopping a generator This assistant is capable of starting and stopping a generator based on battery state and connected load

133 Ignoring AC input This assistant can also be used for ignoring AC by specifying the general flag instead of a relay and adding the general flag user assistant. In this way the grid will act like a backup generator. Only let grid in when the batteries are empty or when the house load is high

134 Using AC output 2 Switch the AC output 2

170 Grounding

171 Grounding: off-grid Do not ground the positive or negative of the PV panels. But ground the PV frames: lightning. Ground close to the battery. Required cross-section: ground cabling should be able to carry a fault current at least equal to the DC fuse rating. The Multi/Quattro chassis must be grounded: basic insulation between AC and chassis

172 Grounding: off-grid with genset One ground only, close to the battery. Required cross-section: ground cabling should be able to carry a fault current at least equal to the DC fuse. A GFCI will be functional only if the chassis of the Multi/Quattro is grounded.
