About 5.5-15kWh Batteries
5.5-15kWh battery systems
This is the capacity band that covers most residential backup: enough to run essential circuits through a typical outage, sized to pair with a 5-10kW solar array. This collection carries 156 systems and modules in that range.
What decides the system
- Backup duration vs backup power. 10kWh runs a few circuits for a day, or a whole home for hours. Decide which question you are answering.
- Continuous output. Capacity without output cannot start a well pump and run a heat pump at once. Check continuous and surge ratings.
- Coupling. AC-coupled for retrofits on existing solar; DC-coupled for new builds with slightly better round-trip efficiency.
- Certification. UL 9540 for the system and UL 9540A test data for the cells - the permit package will want them.
Installation and interconnection
Storage falls under NEC Article 706, with disconnect, rapid-shutdown, ventilation and labelling requirements. The utility interconnection application runs with the solar one, and whether the system exports changes the paperwork. Send the backup circuit list, inverter details and mounting location to the quote desk.
