Forty-eight volts is where serious off-grid systems live — and the ALPHA 5 series is built for exactly that. Native 48V output means it plugs directly into the NOVA 6K and NOVA 12K inverters without voltage conversion losses, stacks to expand your battery bank, and holds up through thousands of cycles. The PRO model adds UL certification for installs that need permits.
