About this product

What it is, and what it is for

rv battery power package with inverter

A complete RV battery and inverter package for off-grid power. Equipped with two high-capacity 12V 200Ah deep-cycle lithium batteries, the two batteries provide 400Ah combined capacity when connected in parallel: a 12V-class bank with 12.8V nominal voltage and 5.12 kWh nominal energy.

Included is a powerful 12V 3000W pure sine wave inverter (KS2 model), designed to deliver clean, stable AC power. The pure sine wave output protects your sensitive electronics, such as laptops, TVs, and medical devices, and safely powers household-style appliances without the risk of damage.

Battery temperature limits: The included 200Ah batteries are the non-heated R-T12200B version, with no built-in heater. Charge only from 0°C to 45°C; discharge from -20°C to 60°C. Do not charge below 0°C. These battery limits do not establish the inverter’s operating temperature range; follow each component’s manual.

High capacity: 400Ah at 12.8V nominal when both batteries are connected in parallel (12V-class system); 5.12 kWh nominal energy.
Pure sine wave inverter: 3000W continuous output with surge capacity to handle startup loads smoothly.
Quiet and clean: No generator noise or harmful fumes — perfect for peaceful camping and indoor use.
Installation: Follow the battery and inverter manuals for operating conditions, ventilation, wiring and protection.
Versatile applications: Suitable for RVs, camper vans, tiny homes, off-grid cabins, mobile workshops, and more.

Whether you’re embarking on a cross-country road trip, working remotely from your mobile office, or simply looking for a dependable backup power source, this package delivers the energy and reliability you need. Enjoy longer off-grid stays, power multiple devices safely, and travel with confidence knowing you have clean, quiet energy at your fingertips.

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.
