Sungold Power Off-Grid Solar Kit 8000W 48VDC 120V/240V LiFePO4 16.07KWH Outdoor Lithium Battery 8 X 450W Bifacial Solar Panels SGR-8K16P
Every other kit in this range assumes you have somewhere indoors to put the batteries. This one doesn’t. The PowerMax 314 is IP65 rated and lives outside, on a wall or a pad, which is the answer when there’s no utility room, no dry basement, or no appetite for a few hundred pounds of lithium inside the house. 16.07kWh behind an 8,000W split-phase inverter with 3,600W of bifacial solar: a refrigerator runs for nearly four days on storage alone.
The battery sets the ceiling here, not the inverter. The PowerMax 314 is rated for 7.68kW of continuous discharge, so sustained output lands around 7,000W at the outlet rather than the inverter’s full 8,000W. Starting surge is unaffected, and very few off-grid houses pull 7kW continuously. But if yours does, our multi-battery kits are the ones to look at.

Sixteen kilowatt-hours sits between our 10kWh and 20kWh kits, and it’s a sensible place to land: essential loads run for days, and the array replaces a full bank in a good day. The bottom rows are capability rather than a daily plan. Heavy 240V loads want to run while the sun is up, and an electric water heater will empty this bank in three hours if you let it.
