The Sol-Ark 15K-2P paired with the Discover Helios 16kWh battery delivers focused whole-home backup for critical loads — refrigeration, lighting, communications, and select appliances. The Sol-Ark 15K switches to battery power within 5ms, keeping computers and sensitive electronics running without interruption. Three independent MPPT controllers handle panels facing different directions or experiencing partial shade. The Discover Helios uses lithium iron phosphate chemistry with 6,000+ cycle life and self-heating that activates automatically at low temperatures, ensuring reliable charging performance down to -13°F. Storage is expandable to 32kWh without replacing existing equipment.
