Energy storage can stabilise fluctuations in demand and supply by allowing excess electricity to be saved. If electricity isn’t stored, it has to be used at the moment it’s generated. In private households, the main energy consumption usually takes place in the evening, when the sun is already setting. Surplus energy produced during the day is normally sold back to the grid. But there is another option – storing solar energy in batteries. By adding a battery to the system, you can use solar energy in the evenings. The more of your PV plant produced energy you self-consume, the more profitable is your solar park and thus, the shorter is the payback period. The most affordable electricity is the production of your own PV plant. By producing solar electricity and maximising self-consumption, you will protect yourself from possible major fluctuations in electricity prices for decades.
If your solar system and battery are large enough, you can run your home mostly on solar power. Choosing the right solar battery is essential to meet your performance expectations. The main questions are how much electricity your solar system produces, how much power you consume and how long do you want to run your appliances during an outage. During the winter, when solar irradiance is low and the productivity of the panels is modest, the batteries have an additional function. During the evening and night you can recharge batteries with cheaper energy, and during the day, when the electricity price is expensive, you can self-consume or sell the stored energy back to the grid.

Huawei Luna battery system for Huawei inverter
Huawei Luna high voltage battery bank can be used with up to and including 10 kW Huawei inverters. The capacity of 1 battery module is 5 kWh and up to 3 batteries (that is 15 kWh) can be connected to one tower. A maximum of 2 towers (that is 6 batteries) or 30 kWh can be connected behind one inverter.
In the event of grid outage, the system will only continue to operate if a back-up box is connected into the system. In this case, the system acts as a UPS (uninterruptible power supply). For single and three-phase systems, the maximum output power is 2.5 kW. The UPS only works for emergency consumers and in one phase.
- The Huawei Luna battery system only works with Huawei inverters
- Huawei SmartMeter is necessary
- Huawei Luna system can be installed only if the inverter is up to 10 kW (including)
- Control module
- 5 kW battery module
- Wall or floor mounting
- Back-up box for three-phase inverter
