Solar Panels System for Motorhomes (RVs)
On the move, the engine alternator is all that is needed, but parked that is not the case and running the engine to charge the batteries is expensive and unpleasant for any neighbours. A motorhome (RV) solar system is then very attractive. Starting with portable solar panels for an RV our advice is to invest in a portable power station. They provide a total energy management, storage, and supply solution for all motorhome needs. They are charged from solar, engine alternator, or mains, they offer 12 and 230v output as well as numerous USB ports.
Technical Considerations
Power Stations have long been the favourite of outdoor campers, as well as motorhome and camper van owners. With the greater storage and inverter capacities now available, they deserve the close attention of off-grid house owners.
In a single package, they provide
- MPPT solar controller,
- a large LifePo4 battery, and
- extensive AC, DC, and USB power outlets.
They can be charged from solar, the mains, a generator, or another external battery.
Power stations can be divided into three broad product types:
- Small portable units designed to be moved around for use as a mobile source of electricity. Most are usually charged by portable panels. They store 1Kw of electricity and offer the same inverter output.
- Medium-sized units with inverter ratings of 2, 3, and 5Kw. Batteries are of 2 and 3Kw capacities and up to 4 can be connected to a single unit. They can therefore either be the primary source of power or form part of a hybrid solution as an extension to a main motorhom solar installation. The 3 and 5Kw models also have a UPS (Uninterruptible Power Supply) option that means they take over instantly and automatically if the main system fails. The 2Kw models are keenly priced, those of 3 and 5Kw remain relatively expensive. None in this category can handle more than 1500w of solar input but mains/generator power can add another 500w.
- Larger units designed to be the primary energy source for your motor-home. They offer inverters of 6Kw and more; storage options go up to 39Kw.
We are distributors of the Bluetti, Zendure, and Hepway ranges. A Bluetti AC200Max is part of our houseboat system. It has been invaluable. These medium-sized units offer an outstanding solution for motor-homes (RVs) of all kinds. The small 1Kw units are very keenly priced and provide a total energy solution for a camper van. The 2Kw models are very keenly priced but the inverter capacity will be a problem for some larger motor-homes. In practice it means that you cannot use more than one domestic appliance at a time. If the dishwasher is in use, no toaster or coffee machine!
There are 3 types of solar panels system for motorhome:
- rigid – the cheapest and the most efficient, but heavy
- flexible – three times the price but 3/4 the weight, and
- portable – the most expensive but needs no installation and can be deployed when and where needed.
In practice for camping vehicles, roof curve will usually militate in favour of flexible, but, despite the cost, the convenience of portable will convince many that they are the right solution – particularly for those having a power station. (See below). We advise installing as much capacity as roof space permits. We offer an electricity use estimator, with a nifty extension that forecasts daily energy production, monthly.

Simple Controllers.
These devices are connected to your solar array and their sole purpose is to charge your batteries. Two technical controller technologies are offered – PWM and MPPT. The former is cheaper but some 20% less efficient, and we do not advise it.
Our chosen suppliers are Epever and Ecoworthy. We have good personal experience with both and they are compatible with both lead/acid and lithium batteries. Capacities run from 20 to 60A and what you need is directly linked to the power output of your solar array. The output of a typical 400w 24v panel is 17A.
Hybrid Controller/Inverters
combine the functions of MPPT solar charge controllers, mains charge controllers, and 230v mains inverter in a single, low-cost, easily installed unit. With 12v batteries, the inverter output is however limited to 1500w. The 3 and 5Kw products need to be connected to 48v batteries.
Our chosen controller suppliers are Epever, EcoWorthy, and EASun with all of whom we have personal experience on solar panels system for motorhome.
THE RIGHT DECISION.
What is right for you will be determined first by the nature of your vehicle’s primary electrical installation. If it is 12v with some 230v, then a hybrid controller/inverter is an excellent solution subject always to not needing inverter output of less than 1500w. If your vehicle is primarily 230v then a hybrid inverter and 48v domestic batteries will be the best solution if you decide against a power station. If you have 12v domestic batteries and need more than 1500w of mains power then a large capacity 12v to 230v inverters will be the only viable solution.
With the steady fall in price, lithum batteries are now a much better choice for both motor-homes and camper vans since they offer longer life, less weight & volume, and much faster charging than lead/acid. We offer both 12 and 48v units from the well known Chinese company EcoWorthy in capacities up to 2400w. Care is needed if they are to be connected to an engine alternator. Please read the information at LifePo4 batteries. Contact Us for advice if that is not clear.
Vans will usually be using 12v batteries, but motor-homes (RVs) may want to consider 48v for greater inverter capacity and then rely on 230v rather than 12v inside the vehicle. The use of domestic appliances like a fridge-freezer, dishwasher, or washing machine requires 220v and an inverter power rating of at least 3Kw requiring 48v batteries.
