Uninterrupted Power Supply

PowerOak’s ESS has UPS function. Your household won’t have to worry about power outages because of natural disasters or other unexpected reasons.

Save Money

Solar panels charge the ESS battery. Use the stored battery energy for your nighttime peak consumption period and become more independent from utilities. Charge the battery by lowering the rate during deep night, and use the charged electricity for your morning peak consumption period–effectively lowering your electricity bill.

Earn Money

Solar energy fulfills household electricity needs first, then charges the battery. After the battery is fully charged, excess electricity can be sold to the grid.

Control your power consumption anywhere anytime

Along with PowerOak’s all-in-one solar ESS, the user will get a free APP, where households can see their power generation and consumption anytime and anywhere.
