400W Complete Solar Kit with Batteries for Camper Vans, RVs and Off Grid Sheds
This 400W 12 volt complete solar kit with batteries is built for people who want real power in a medium to large camper van, RV, hunting cabin or garden shed without piecing everything together. You get four high efficiency 100W N type solar panels, a 40A MPPT charge controller, a 2000W pure sine wave inverter, all the wiring and fusing, plus your choice of two 100Ah AGM batteries or two 100Ah smart lithium batteries. The result is a clean, quiet power system that keeps fridges, lights, fans, tools and chargers running on weekend trips or in a small off grid setup.
400W Complete Kit with Two 100Ah AGM Batteries
Pick the AGM version if you want a tough, familiar battery setup that just sits and works. The Renogy 400W complete kit with two 12V 100Ah AGM batteries gives you 400W of solar feeding a 200Ah, 12V AGM bank through the Rover 40A MPPT controller, with a 2000W 12V pure sine inverter turning that into clean 115V AC for common household appliances.
Four 100W 16BB N type panels do the charging. They use high grade N type cells with up to 25 percent efficiency, so you squeeze more energy out of limited roof space and still see useful output in mixed or partial shade. Each panel is about 34.1 x 22.8 x 1.2 inches and weighs roughly 13 pounds, easy to handle on a van or shed roof.
The two 12V 100Ah deep cycle AGM batteries are rated at 100Ah at the 10 hour rate, with a charge voltage target of 14.4 to 14.8V. Each battery is about 13.1 x 6.9 x 8.6 inches and weighs around 64 pounds, so they sit like a proper house battery bank, not a toy.
Everything in the kit is sized to work together: Z brackets to mount the panels, Y branch connectors to wire the array, tray cables to reach the controller, ANL fuse and holder on the battery side, waterproof inline fuse on the PV side, heavy 4AWG and 8AWG cables where they belong, plus battery inverter cables, BT 2 Bluetooth module and a 500A battery monitor with shunt so you can actually see what is going on with your system.
This setup is a strong fit if you want proven lead acid, are not chasing maximum weight savings, and prefer something you can install once and trust for years.
400W Complete Kit with Two 100Ah Lithium Batteries
Choose the lithium version if weight, usable capacity and cold weather performance are at the top of the list. The Renogy 400W complete solar kit with lithium batteries swaps the AGM pair for two 12V 100Ah smart LiFePO4 batteries with Bluetooth and self heating, while keeping the same panels, Rover 40A MPPT and 2000W inverter.
The solid state lithium iron phosphate batteries are much lighter, around 26.9 pounds each, with a compact footprint of roughly 10.6 x 7.6 x 8.1 inches. Built in Bluetooth lets you check state of charge and battery status directly from your phone, and the self heating function is designed to protect charging in cold climates by warming the cells when needed.
With lithium, more of the rated 100Ah per battery is usable on a daily basis, so your 400W solar kit with 200Ah of LiFePO4 supports longer runtimes and deeper discharge without the same penalty you see with AGM. That makes a big difference if you are running a fridge, fans, lights, laptops and networking gear into the evening or through poor weather.
The rest of the package mirrors the AGM kit: four 100W N type panels, Rover Li 40A MPPT, 2000W pure sine inverter, Z brackets, Y connectors, tray cables, fusing and inverter cables, plus the BT 2 module for controller level Bluetooth monitoring.
Built For Fast DIY Installs and Travel
Both versions of this 400W complete solar kit are designed so a reasonably handy person can install them with basic tools.
The panel frames use PA66 GB30 reinforced corners, which help with safe handling on ladders and roofs and stand up to vibration on the road. The included Z brackets are straightforward to mount on van, RV or shed roofs, and the solar Y branch connectors, pre cut 20 ft 10AWG adaptor kit and 8 ft 8AWG tray cables simplify PV and battery runs to the Rover controller.
With the 2000W 12V pure sine inverter in the kit, you can plug in typical small appliances once everything is wired: fridges, laptop bricks, phone chargers, small microwaves, coffee makers and similar loads within the 2000W rating, with 4000W surge available for motor starts.
The whole system is compact enough for a medium or large camper van electrical bay or a small power corner in a shed, garden office or hunting cabin, while still giving you real off grid capability.
Smart Charging, Heat Management and Monitoring
At the center of the charging system is the Rover Li 40A MPPT charge controller. It accepts up to 100V DC PV input and up to 520W of PV at 12V, so a 400W array sits well within its limits. Automatic 12V or 24V recognition means it can support future changes, and 40A of output is plenty for this battery size.
An external temperature sensor is included so the controller can adjust charge voltage based on real battery temperature. That protects against undercharging in the cold and overcharging in heat, with a rated operating span from about minus 40°F up to 149°F. For people storing vehicles outside or parking in real weather, that protection matters.
The kit also includes a BT 2 Bluetooth module so you can see solar input, battery voltage, charge stage and more from the Renogy app, and for the AGM version a 500A battery monitor with shunt gives a clear state of charge picture instead of guessing from voltage alone.
