Mobile service

Mobile RV solar, inverter and battery service

Off-grid power turns an RV, van, trailer or boat into a place you can stay without hookups, but it only works when every part of the chain is healthy. A bad connection, a wrong setting on a charge controller, a failing converter or a tired battery bank can leave you with dead batteries and appliances that shut off. A mobile tech can come to your site, test the system from the panels on the roof to the batteries and the inverter, and find where power is being lost. Tell them what equipment you have, what is not working, and share photos of the battery compartment, the controller and any display screens.

Quick answer

Yes, most solar, inverter, converter and battery problems can be diagnosed and repaired on site. A mobile tech can test panels, charge controllers, inverters, converters, transfer switches, wiring and battery banks, and can install or upgrade many systems in place. Complex custom builds or major rewiring may take more than one visit.

Signs you need RV solar, battery and inverter service

  • House batteries drain faster than they used to
  • Batteries not charging on solar, shore power or the generator
  • Inverter shows a fault, beeps or shuts off under load
  • Outlets dead when off shore power
  • Solar charge controller shows little or no input on a sunny day
  • Lights dim or flicker when something turns on
  • Warm or melted connections or a burning smell near the batteries
  • Battery monitor readings that do not make sense

Battery banks can deliver very high current, and a short can cause burns or fire. Do not touch damaged, swollen or hot batteries, and disconnect shore power before any work. If you smell burning or see smoke from the battery or inverter area, shut off power if you can do it safely, get clear and call for help.

Common causes

Worn or mismatched batteriesBatteries lose capacity with age and deep discharges. Mixing old and new batteries, or different types, drags the whole bank down.
Loose or corroded connectionsA single loose or corroded terminal can waste power, cause voltage drops and heat up. It is one of the most common and most important things to check.
Charge controller settingsCharge settings need to match the battery type. Lithium and lead-acid batteries charge differently, and wrong settings can undercharge or damage them.
Converter or charger failureThe converter charges batteries from shore power or a generator. When it fails, batteries slowly drain even while plugged in.
Inverter overload or faultRunning more than the inverter can handle, low battery voltage or an internal fault will make it shut down or alarm.
Panel shading, dirt or damageShade, dirt, cracked panels and damaged roof wiring or connectors cut solar input.
Parasitic loadsDetectors, control boards and other always-on devices draw small amounts of power that add up when the RV sits.

What gets done where it's parked, and what needs a shop

Usually done on site

  • Battery bank testing and replacement
  • Checking, cleaning and tightening connections, fuses and breakers
  • Charge controller testing and configuration
  • Inverter and inverter/charger diagnosis and replacement
  • Converter and transfer switch diagnosis
  • Solar panel, roof wiring and connector inspection
  • Battery monitor installation and setup
  • Installing or expanding many solar and battery systems

May need a shop or lift

  • Large custom systems that need extensive rewiring through walls and cabinets
  • Fire or heat damage that has spread beyond the battery area
  • Upgrades that need new battery compartments or structural mounting changes

Every mechanic's setup is different. The one who accepts your request will tell you if your job needs a shop.

Before the mechanic arrives

  • Note what equipment you have: battery type, number of batteries, panels, controller and inverter
  • Take photos of the battery compartment, the controller, the inverter and any error screens
  • Describe how you use power off-grid and what shuts down or runs out first
  • Plan for the tech to need roof access for panel checks and clear the area below
  • Have shore power available if possible so charging can be tested

Photos of warning lights, leaks or damage help the mechanic bring the right parts. You can add up to five with your request.

Questions to ask when you get a quote

  1. Are my batteries worn out, or is the charging system the problem?
  2. Are my charge controller and inverter set up correctly for my battery type?
  3. Is my wiring and fusing sized properly for my inverter?
  4. Can my converter charge the batteries I have, or does it need an upgrade?
  5. What size system would fit how I actually use power?
  6. Will you show me how to read my battery monitor?

RV solar, battery and inverter service: questions and answers

Many can. Panel mounting, roof wiring, charge controllers, inverters and battery upgrades are usually done in place. Very large or custom systems may need more time, so describe what you want when you ask for a quote.
The batteries may be worn, the controller may not be set for your battery type, panels may be shaded or dirty, or your loads may be larger than your system can keep up with. A tech can test each part and measure what you are really using.
Often yes, but it is more than swapping the batteries. The converter, charge controller, inverter charger settings and sometimes the alternator charging need to suit lithium. Ask a tech to check the whole charging system.
A converter takes shore or generator power and turns it into 12-volt power to run the RV and charge the batteries. An inverter does the reverse, turning battery power into household-style power for outlets. Some units do both, and either can fail.
Many do. For starting batteries on the truck or motorhome chassis, see battery replacement. For the rest of the RV's systems, see mobile RV repair.
