The new battery system keeps its modular design, with capacity offerings from 9-18 kilowatt-hours per battery cabinet. You're also getting a much needed power boost, with 5.1 to 10.3 kilowatts of output, depending on how many modules are in the battery cabinet.
If you need a small capacity upgrade, you can add another module to your existing battery cabinet, instead of buying another giant battery. One PWRcell 2 battery cabinet can store 9-18kWh of energy, depending on how many modules are in the cabinet. One cabinet can hold up to six modules.
You can recharge your battery via grid power when rates go back to normal. If you have solar panels, a home battery can also help make sure none of your solar energy goes to waste by storing any excess solar energy your panels generate in a battery.
If one battery module is faulty and new battery module needs to be replaced. If two battery modules need to be removed. Before adding a new battery module the battery modules in use need to be charged or discharged to match the SOC of the new battery (it should be within 10% SOC difference as mentioned above).
Home batteries function as an electric alternative to gas-powered backup generators. The battery stores electricity (either charged from the grid or solar panels) and deploys it to certain parts of your home in the event of an outage. You can also use home batteries to help you avoid expensive time-of-use rates.
Set the SOC Upper Limit to 100% and the SOC Lower Limit to 20 % (calculated value for the new battery). Apply the settings. By charging the battery to 100%, a calibration is performed to improve the accuracy of SOC. (This takes some time, can be omitted and the target SOC value can be directly set and charged or discharged to the target SOC).
