Our approach
Shore, generator, battery
A coach has three power sources and a lot of switching between them. Shore power and the generator meet at the transfer switch. The inverter-charger turns battery power into household power and charges the batteries back up. Solar adds to the batteries when the sun is out.
When something works on shore power but not on batteries, the fault is usually somewhere in that chain: an inverter setting, a battery bank that can't deliver current, a loose cable or a transfer switch contact. We test each stage to find where power stops.
Lithium upgrades can be a real improvement for coaches that boondock or run residential fridges, but charging profiles, alternator charging and battery monitoring all have to match the new chemistry. We look at the whole system before recommending one.

FAQ
Electrical & Lithium questions
The inverter may be off or faulted, the battery bank may be too weak to deliver current, or a high-current cable may be loose or corroded. We test the inverter output and the battery side to find which.
It depends on how you use the coach. Owners who boondock, run a residential fridge on the road or want lighter batteries often benefit. The charger, alternator charging and monitoring must be set for lithium too.
Common causes are low battery voltage, overload, overheating or a ground fault. The fault code on the inverter or remote panel tells us where to start, so take a photo of it.
Use 50 amp when your coach is built for it and the site offers it. On 30 amp you will need to manage loads, usually running only one A/C unit at a time with fewer appliances on.
