About 15-30kWh Batteries

15-30kWh battery banks

15-30 kWh is whole-home backup territory: enough to ride out a multi-day outage with sensible load management, or to shift a full day of solar production. This collection carries 122 systems and modules in that range.

What decides the system

  • Duration vs power. 30kWh may run the whole house for a day or the essentials for three; the continuous output rating decides which loads can run simultaneously.
  • Inverter architecture. High-voltage battery systems pair with specific hybrid inverters; 48V systems are more flexible across brands.
  • Certification and permitting. UL 9540 for the system, UL 9540A cell data, and Article 706 for the installation.
  • Physical footprint. 30kWh is not a wall-mount afterthought - plan the equipment room, clearances and lifting.

Ordering

Send the backup circuit list, solar array size and inverter model to the quote desk and we will confirm capacity, output and interconnects.
