The use of energy storage in combination with a photovoltaic system in a single-family house brings a number of immediate advantages, but also those that will arise in the near future due to the rapidly increasing electricity prices. SAVING - Significant reduction in electricity bills (in some cases even to 0) thanks to an efficient model of energy production and use. ENERGY CONTINUITY - immunity to network overload, possibility of supplying energy to the network off-peak according to own needs. SAFETY - the battery consists of durable and safe LiFePO4 cells with systems that constantly monitor the operation of the device, which ensures uninterrupted operation of your photovoltaic system. TECHNOLOGY - PowerNest is over 98% efficient, allowing you to use almost all of the electricity generated by the solar panels at a later date, allowing for a shorter payback period. ECOLOGY - the island consumption of green electricity from a photovoltaic system is the best way to reduce your CO2 emissions and thus contribute to a more sustainable development of your household. CONVENIENCE - thanks to the use of a suitable inverter or external device, it is possible to protect your home from blackouts so that you can enjoy your life undisturbed - whether you are listening to music, reading a book or chatting with friends. EXPANDABILITY - You can realize your investment with a PowerNest energy storage and if you decide you need a larger energy bank, you can simply get another PowerNest. In this way you can connect up to 8 devices and achieve a capacity of up to 40 kWh.
