Produce your current by yourself There is no easier way!
We offer the solution: Sinusstrom Sinushammer For the first time it is possible to have a simple self sufficiency by using a photovoltaic system and a combined battery storage with the Sinusstrom Sinushammer. The phase with the main consumers of the House is fed at the house connection box by the main-synchronized but not on-grid working inverter from the PV plant and the battery storage system respectively. In this way, a high degree of self-sufficiency can be achieved. As soon as the batteries fall below 30 % of their nominal capacity and no more PV electricity is generated, there is a changeover to mains operation. With only 8 PV panels, which are installed on the unused roof area or in the garden, you can install up to 2,000 Wp. This corresponds to a power generation of 2,000 kwh a year and the power consumption of a family of three. The usual consumers of a household are connected to the inverter which is transforming the generated direct current of the connected solar plant into alternating current. The consumer of a household will be divided into two electric circuits:» Consumers with high performance: electric kitchen stove» Consumers with low performance: refrigerator, lighting, etc. Consumers with low performance are connected to the in-house network and are operated by the current self-generated Advantages: low financial burden independence, you run your own power plant constant current availability you will actively contribute to environmental protection no permission required no EEG allocation no network load The Sinusstrom Sinushammer in concise:» 3-5 kwh storage capacity» compact design» no hazardous voltages by low-voltage system» no network supply, that means the facility is exempt from authorization» long-proven quality batteries from reputable manufacturers» backup function in case of power failure and reserve function» safe operation by single-cell monitoring» easy to read display of all messages and operating states» Dimensions: 600 x 550 x 630 mm
PV- & battery-electricity How it works In the normal case, the PV panels are optimally illuminated by sunlight and produce Energy. The required current passes directly to where it is needed. The energy which is left is stored in the battery system. The storage provides the energy available which is produced during the day. Therefore even at night the energy requirements can be met. As soon as the batteries fall below 30 % of their storage capacity and no more PV electricity is generated, there is a changeover to mains operation. By this operation of the inverter all home appliances such as electrical appliances, lighting, computers, etc. run as normal. Once the battery is sufficiently charged, there is a switches back to the self-supply operation. Once the lithium cells are almost fully surplus production» Optional, if having a full storage system and surplus production the storage system can be added by a cartridge heater so that the generated electricity can be converted into heat in order to fill a heat storage vessel. loaded it is switched to a reduced charged current in order to ensure a high number of cycles of the storage system for long-term.
LiFePo Battery BMS PV-Management load management photovoltaic plant (48 V) house connection box 1-phase duration consumer 1- & 3-phase little consumer In case of mains failure, an immediate switch to battery mode occurs; the system and the connected loads are therefore fully independent. Feeding back into the public grid or the in-house network is not possible, so there is no need for permits. The battery has a multichannel analog battery management system which initiates a load shedding of the battery in case of error (over voltage, under voltage, over temperature). An easy status display and a error indication is given by the LEDs of each cell.
Modular construction & laying information It is recommended to use polycrystalline standard photovoltaic panels. The number can be chosen almost freely on the depending on the roof size. For different electrical characteristics of the PV panals the storage can be adapted on request. We offer storage systems in various sizes as well so that they can be adapted to the individual requirements. Inverters are also available in different performance ratios. The following should be considered:» The inverter should have a little more power than the connected loads. The consideration should be made whether new equipment is going to be purchased in the near future, which increase the energy consumption.» The performance of the PV system should not be oversized compared to the storage capacity in accordance with Table below Scope of functions» self-supply from PV & storage system» isolated operation in case of power failure (automatic)» automatic mains switch (at 30% SOC automatically)» mains synchronized operation» battery management (charging with maximum power and following power reduced complete charging including cell balancing)» BMS-controlled load shedding and line protection» public grid feeding is not possible (without authorization)» modular construction (expandable)» excess energy can be converted into heat (switching output already provided)

Setting and switching options» ON / OFF (OFF means mains operation)» switching network priority or priority battery & PV» switching to 0 % SOC (in case of mains failure longer selfsufficiency is possible) Efficiency (by using a 2 kw unit)» efficiency (European) inverter: 95%» standby losses: 20 W» losses in the switched off state: 1.5 W Installation instruction» The consumers supplied for the self-sufficiency concept should be bunched into a phase in the house connection box. It should be ensured that the power shall not be higher than the rated power of the inverter.» With the parallel connection of the photovoltaic modules and the subsequent distributing main, adequate wire cross sections have to be chosen due to high currents. The DC input of the inverter already has a line protection (fuses) and a reverse current diode.
Why you should buy our storage system Rising electricity prices Rising electricity prices burden the budget of every household enormously, and currently a higher electricity price is forecasted again. The annual rate of growth vary slightly but add up to 7 % in longtime average.

It is no longer profitable to feed the generated power into the grid. In addition, owners of existing plants can use only a fraction of the energy generated themselves. The largest part must be fed in the grid and is lost. The Sinusstrom Sinushammer offers the solution: The Sinusstrom Sinushammer saves the energy PV energy produced during the day in a lithium iron phosphate battery and release this energy at night when no new energy is created. Therefore you have your own private power supply. Increasing pollution of the environment Pollutions caused by heating equipment, fuel or exhaust fumes pollute our environment more and more. Our raw materials are limited and are no longer sufficient. In addition, these raw materials are found in a few regions of the world only, very often long journeys are necessary. This pollutes the environment balance negative again and sustained yield should look differently. With your own storage system you have your own energy management and you release the power grids as well. That is why you choose the Sinusstrom Sinushammer! This one offers the opportunity to reduce your energy costs and contribute to protect the environment significantly!
