About this product

What it is, and what it is for

A dependable power solution for RVs, travel trailers, camper vans, and off-grid adventures. This package features four 12V 100Ah deep-cycle batteries combined with a free 12V 3000W pure sine wave inverter to supply AC power for compatible appliances within the inverter’s operating limits.

Total Storage Capacity: 400Ah at 12.8V nominal when all four batteries are connected in parallel (12V-class system); 5.12 kWh nominal energy.
Pure Sine Wave Output: provides pure sine wave AC output. Confirm each appliance’s voltage, frequency, continuous-power and startup-load requirements before use.
No Fuel Combustion During Use: battery-powered operation does not require a running fuel engine. The inverter’s cooling fan may produce sound; follow installation and ventilation requirements.
Ideal For: RV living, boondocking, road trips, remote work, and outdoor travel.

Plan your on-the-road power needs around appliance loads and available battery energy. Runtime varies with usage and operating conditions; the batteries require recharging.

Nominal and Estimated Usable Battery Energy

Nominal battery energy: 5.12 kWh. Estimated usable battery energy: 4.864 kWh (95% of nominal). No separate usable-energy rating is stated in the linked ROCKSOLAR battery specification, so this is a planning estimate, not a manufacturer-tested usable-energy guarantee. Actual available energy varies with temperature, load, battery age, BMS limits and system settings. AC energy is lower after inverter losses. Always follow manufacturer charging and discharge limits.

Common questions

Before you order.

If yours isn't here, ask an engineer. It costs nothing and it's the step most people skip.

What if I'm not sure this is the right product?

Ask before you order. Send us what you need to run, or your pool or well figures, and an engineer will confirm the choice — it costs nothing. Or use the finder below, which sizes from what you actually run and shows its reasoning.
