When the solar container battery capacity drops below what level it needs to be replaced

What happens if the battery voltage falls below the sustain level?

When the battery voltage has fallen below the sustain level it will be charged back up to the sustain-voltage-level using power from the grid. The charger will ensure that voltage level is maintained - using power from the grid when necessary.

What happens if a battery is used too much solar power?

Excess solar power will also be used for battery charging. Sustain mode is exited when solar-charging has been able to raise the battery voltage 0.1 V above the sustain-voltage-level. Normal operation will then continue - with the battery providing power when insufficient energy is harvested from the PV array.

What happens if a solar system reaches a low SoC limit?

When weather conditions change, and more solar energy becomes available, the system will once again lower the Low SoC limit, day by day, making more battery capacity available for use (it will eventually return to the user-preset limit) - whilst still ensuring that the battery SoC ends each day at or close to 100%.

What is Sunway ESS battery energy storage system (BESS)?

Sunway Ess battery energy storage system (BESS) containers are based on a modular design. They can be configured to match the required power and capacity requirements of client’s application. Our containerised energy storage system (BESS) is the perfect solution for large-scale energy storage projects.

How many households can a solar Container Supply?

Based on an average power consumption of a 4-person household of 4000 kWh per year and a location in Southern Germany, the solar container can supply approx. 32 households with climate-friendly electricity. At a location in Southern Europe it can even be up to 50 households due to the high solar radiation.

What happens if a battery capacity is set to 60%?

When set to 60%, all capacity between 60% and 100% will be used to optimize self-consumption. And 0% to 60% will be used in case of a mains outage. Note that the minimum SoC parameter - as configured in the CCGX - may be amended on a daily basis by the BatteryLife algorithm. Battery Voltage. See Dynamic Cut-off section, further down below.
