SunGold Power 10kW Off-Grid Solar Kit vs Ozark Mountain Offgrid 2.2kW Solar Kit

The SunGold kit is the whole-house system: 10kW inverter, 25.6kWh of LiFePO4 storage and 6.6kW of panels, UL1741 listed and parallelable to 60kW. The Ozark kit is a starter: 6kW LuxPower inverter, 5.3kWh of battery and 2.2kW of bifacial panels, sized for a cabin, shop or RV and built to grow. Buy SunGold for a full-time off-grid home with HVAC, a well pump or shop tools; buy Ozark if you want a smaller, expandable first system. Owners praise SunGold's design help and support; Ozark's kit is simpler and lighter, but it carries no written warranty and its battery bank is about a fifth the size.

• Choose the SunGold Power 10kW kit if you are powering a whole house year-round and want large storage, split-phase output and room to parallel more inverters.
• Choose the Ozark Mountain 2.2kW kit if you are starting a cabin, shop or RV system and want a smaller, expandable package with mounting and wiring included.
