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.
