The Comvolt 4200 system is designed for people who want a clean, reliable power solution and want to get up and running quickly, without becoming an electrical expert. Instead of researching batteries, inverters, fuse blocks, breakers, wiring sizes, control panels, and how they all work together, Comvolt packages the critical components into one compact, compatible system that is already sized, protected, and tested to work as a whole. That means fewer decisions, simpler installation, and a much faster path from unboxing to usable power. The result: a smaller, more manageable system that covers real-world needs and just works. If you plan to run higher draw appliances or want more usable battery capacity, check out the Comvolt 6000.
The Comvolt Core and Complete Systems deliver an integrated power kit experience similar in concept to EcoFlow Power Kits, combining battery storage, fused AC and DC distribution, and centralized monitoring. Comvolt focuses on the essential functionality most van and RV builds need, while EcoFlow Power Kits offer a more advanced, premium solution with deeper integration and expanded features. Think of it like this:
Effortless Connectivity and Comprehensive Monitoring
The 7" Smart Display provides real-time visibility into battery status, charging, and power usage. It connects directly to the Comvolt system and supports up to 10 battery units using a proprietary communication protocol.
The Comvolt PDUs act as smart, fused power distribution hubs between the Comvolt 4200 power station and your appliances. Instead of running multiple loose wires directly from the battery, the PDUs centralize power distribution, protect each circuit, and allow both manual and screen-based control from one clean location. Both PDUs connect directly to the Comvolt system and the 7" Display.
Key Benefits
Safely distributes high-current 12V DC power to accessories like lights, fans, water pumps, fridges, heaters and other devices. Replaces a traditional 12v fuse block.
Safely distributes 120V AC power from the inverter to appliances such as outlets, induction cooktops, air conditioners, microwaves, and tools.
If you’re unsure whether Comvolt, Victron, or a full Ecoflow Power Kit system is right for your build, contact us. We’ll help you compare options and choose the best path forward.
Yes. The Comvolt 4200 was engineered for high-draw 12V air conditioning systems and can deliver overnight runtime in many real-world builds. Actual runtime depends on temperature, insulation, and air conditioner duty cycle.
Comvolt combines the battery, inverter, charging, fused distribution, and monitoring into one coordinated system. This removes the need to design and wire a custom electrical setup from scratch, saving time and reducing complexity.
Yes. The Comvolt 4200 integrates easily with most camper van and RV electrical systems using standard 12V connections, Anderson connectors, and AC output.
The AC and DC PDUs are smart, fused power distribution hubs that safely route power from the battery and inverter to individual circuits. They replace traditional fuse blocks and breaker panels with cleaner wiring and centralized control.
The DC PDU powers 12V devices such as lights, fans, water pumps, fridges, diesel heaters, USB outlets, and other accessories. Each circuit is individually protected and controllable.
The AC PDU distributes 120V AC power from the inverter to outlets and appliances like induction cooktops, microwaves, laptops, tools, and small air conditioners.
The optional 7" Smart Display provides real-time system monitoring and allows you to turn individual AC and DC circuits on or off from a single screen.
The system supports three charging methods: solar panels, vehicle alternator charging, and shore power. Integrated charging components automatically manage power input to protect the battery.
Yes. Multiple Comvolt battery units can be connected in parallel to expand total capacity up to 100kWh, making it easy to grow the system as your power needs increase.
The Comvolt 4200 is ideal for van builders, RV owners, and off-grid users who want a reliable power system without designing and troubleshooting a full custom electrical build.

The Comvolt 4200 (with AC/DC PDU and 7-inch screen) is a game-changer for any setup. Super easy install—mostly plug-and-play with minimal wiring. No fuss, no extra components to hunt down. It’s compact, portable, and incredibly versatile: works flawlessly off-grid in a van, car, shop, home, or anywhere else. Everything’s built right in, so you get clean power without the headache of piecing together a bunch of parts. Expandable too if you need more juice later. Hands down one of the most convenient, reliable portable power stations out there. Nice work, Comvolt team—I love it! Highly recommend. Thank you Orion Van Gear Reds Custom OffRoad
Thanks so much for the great review. We’re stoked you loved the Comvolt 4200 and really appreciate the shout out. Also loved your YouTube video on it, great walkthrough. For anyone reading this, be sure to check out Reds Custom OffRoad’s YouTube video to see the system in action.
Can you hook up any solar panels to it and it charges or do you need extra things to add?
Yes, the 4200 has one XT60 solar input. You can hook up to 400W of solar (20-45v).
Very nice, well built and affordable panels.
I just finished the install of the MaxxFan Deluxe, replacing a stock vent fan in our new Class C MH. Following the written (and online ‘how to’ videos) guidance, the install was straightforward. Most of the 3.5 hour job was spent cleaning off the old lap sealant in preparation for the new fan.
Fan works well in all functions. Thank you MaxxAir for a good product and thank you Orion for a great sales price!

So quiet. Easy to install. We received the wrong item from Orion (black interior control panel vs white) We contacted them via email and they immediately gave us several options to make it right. The fan works great and the customer service Orion provides is top notch.
Hi Jamye, Sorry about the mix-up with the interior panel, but we're glad we could resolve it quickly. Thanks for your kind words and video! Its a slick fan!
Orion went the extra mile for us. We had an incident of the Van colliding with a concrete pillar. The Hook for the surfboard rack was torn off. We had a trip planned in 5 days. Orion was able to get us a new hook and clamp and we were able to go on our trip with the boards. Thank you Orion you Rock
supper product I had been looking for a crossbar rack system for my van's roof rack for more than a year, and this is perfect I did have to enlarge the holes on the foot piece of the cross bar to 11/32 to fit my roof rack hex bolts for mounting, easy peezy
