2.Description 2.1 General System Description Powervortex 3100 / 3700TL hybrid system is designed for the new installation of solar battery hybrid system. Figure 1 Powervortex 3100 / 3700TL hybrid system The system includes four modules: PV inverter, BM024 battery manager, lithium battery packs and energy meter. A B C D Figure 2 Main system components 1) SolDate 3100 / 3700TL PV inverter (Storage ready) The PV inverter converts the DC power generated by PV modules into AC power. The generated electricity from PV is used by the household loads, charged into the battery packs or fed into the grid. 2) BM024 battery manager In connection with the SolDate 3100 / 3700TL via DC bus line, BM024 battery manager charges / discharges the battery packs according to commands from integrated energy management unit. 3) Battery packs 5
Battery packs stores the energy generated from PV generator. Generally, each battery module capacity is 2.4kWh; so two battery modules can constitute 4.8kWh battery pack. 4) Energy meter The 1-phase bi-directional energy meter is for data collection and communication. With the meter data, the hybrid inverter decides when to charge / discharge the battery packs. 2.2 System connection The four main components are connected as displayed in Figure 3, which can not only optimize solar energy self-use and realize peak shaving, but also protect family from power outages.

3. System installation 3.1 Unpacking the device 3.1.1 Before unpacking All products are thoroughly tested and inspected before they re packed and transported. Although they re shipped in reliable package, damage during transportation could still occur. It is important to carefully inspect the shipping package prior to the installation. If any external damage on the package makes you suspect the device could be damaged or if you find that the device is damaged after unpacking it, report the damage immediately to your distributor or the goods forwarder. If it becomes necessary to return the device, please use the original packages in which they were delivered. The gross weight of SolDate 3100 / 3700TL is 25kg, for which BM024 is 10kg. To avoid injury, take the device at the two holding grips that are visible on the side and take the device outside the package. Ensure a second person to assist in the unpacking and installation of the devices. 3.1.2 Mounting 1. Don t install the device in direct sunshine. External heating from exposure to the sun may cause excessive internal heating. This may result in output power being reduced in order to protect the internal components from damage. 2. The SolDate 3100 / 3700TL weights 25 kg, the BM024 weights 10 kg. The installation wall must be vertical and can carry the weight of the devices. 3. Install the Powervortex 3100 / 3700TL in a location that maintains an ambient air temperature that is less than 45 C. The Powervortex 3100 / 3700TL may reduce its output power if the ambient air temperature exceeds 45 C (The cooler the air temperature, the longer the life expectancy of any electronics device). 4. The install position for Powervortex 3100 / 3700TL and battery cabinet, please refer to the device dimension figure and installation space figure (Figure 4~Figure 6). 5. The system should be installed in a location that is inaccessible to children. 6. The device is designed for indoor installation (IP20). 7. We recommend that you mount the device at eye level to ensure optimum user comfort. 8. Do not install the system on flammable construction materials, in areas close to flammable or explosive materials. 7

5.3 System operating instructions 5.3.1 On-grid operation The hybrid inverter has 2 options of operation mode: 1. Self-use Mode If there is enough sunshine, PV energy supplies the load first and then charges battery packs; if the load power is covered and battery is full charged, surplus energy will be fed into the public grid to acquire the FiT. If there is no sufficient PV energy, the system discharges the battery pack first; if PV power and battery discharging power is smaller than the load power, then the grid co-supply energy to the load. 2. Time of Use Mode (Peak Shaving) The system charges the battery packs at off-peak time (pre-set charging time); discharges the battery packs at peak time (pre-set discharging time). 5.3.2 Off-grid operation The Powervortex 3100 / 3700TL hybrid inverter has integrated backup function. Note: maximum charging current, maximum discharging current, discharging stop voltage and charging stop voltage should be set before commissioning to maintain battery s lifetime. These parameters are set in LCD screen. 5.4 System maintenance When maintaining the system, power off the Powervortex 3100 / 3700TL. Please obey the following operations: 1) Turn off the AC breaker, which means cut the inverter off the grid 2) Turn off the DC breaker of battery cabinet 3) Turn off DC switch of SolDate 3100 / 3700TL 4) Waiting at least 15 min. before maintenance 5) After disconnecting all the cables, please move the inverter to a proper position for maintenance Note: if the system is not used for a long time, please turn off the whole system for safety.

6 Troubleshooting 6.1 Safety during Troubleshooting High electric voltage! Risk of death or personal injury by electric shock! Never work with live wires! It is prior to all connection and maintenance work. Make sure that the AC and DC wires are not charged. The connection area should only be opened by a licensed electrician. Warning! Danger from residual voltage out of capacitors. You must wait until the capacitors have fully discharged. Discharge takes around15 minutes. Caution! Danger from inadequate grounding. An inadequate grounding conductor connection can cause serious injuries to persons and damage to properties. 6.2 Faults A fault can be divided into two catalogues: a permanent failure and a temporary failure. A permanent failure is defined by a fault having been present for more than 15 minutes and cannot be acknowledged by inverter s auto-restart. Unlike permanent failure, a transient failure" is automatically acknowledged by the inverter. 6.3 Fault Messages and Actions List When failure occurs, warning codes will be displayed on the LCD screen. The latest 20 fault codes will be stored in the EEPROM. Check the history fault information via long-pressing the key ESC. Detailed fault definitions are listed as below: Fault messages Explanation Action E01 The DC injection of grid current is out of Contact the service if the error occurs range. repeatedly.

The fault can only be acknowledged after the cause of the fault has been eliminated. To acknowledge the fault messages, press the ESC key or turn the GMDE inverter off with the DC switch. Wait for a while and turn the device on again. 31
