Solar & Battery Power

Not sure where to start? Read our Off-Grid Solar Battery Bank Sizing before you buy.

Power your home, cabin, RV, or job site off-grid with solar and battery systems from Urban Supply Inc. Our solar panels, lithium batteries, inverters, charge controllers, and complete power kits come from trusted names like EG4, ECO-WORTHY, and more.

Whether you're building a whole-home backup system, going fully off-grid, or adding portable power for adventures and emergencies, you'll find the components and complete kits to capture, store, and deliver clean energy — with LiFePO4 batteries rated for thousands of cycles.

What to look for

Size your system to your daily watt-hour usage, match battery voltage (12V, 24V, or 48V) to your inverter, and confirm panel wattage and charge-controller capacity. For backup power, factor in surge loads from motors and compressors. Our team can help you spec a complete system.

Why buy from Urban Supply Inc: we're an authorized dealer for every brand we carry, so everything ships new with the full manufacturer warranty. Enjoy free shipping on orders over $299 (certain exclusions apply), shipping insurance, and US-based expert support from a team that knows these products. Browse the collection below and order with confidence.
