(559) 246-5125Your Class B van should run your fridge, AC and coffee maker without a generator or a campground hookup. CTS RV Repair designs and installs complete Victron electrical systems for Class B vans in Clovis, Fresno and surrounding towns. The same tech who designs your system installs it, start to finish.
What We Install
- Lithium (LiFePO4) battery upgrades: more usable power, a fraction of the weight of lead-acid, and thousands of cycles.
- Inverter/chargers: Victron MultiPlus-II systems that run 120V appliances off your batteries and charge fast from shore power.
- Solar: roof-mounted panels with Victron SmartSolar MPPT charge controllers, sized to how you camp.
- Alternator and DC-DC charging: Victron Orion DC-DC chargers, plus second-alternator systems that recharge your house bank while you drive.
- Monitoring: Cerbo GX with touch display and SmartShunt, so you see exactly what’s charging and what’s drawing power, from the van or your phone.
- Clean distribution: Lynx distribution with proper fusing, so the system is safe, serviceable and easy to expand.
- AC soft start: run your rooftop AC on battery and inverter power.

Lithium Battery Upgrade
"Earlier this year Mitchell did a major lithium batter and inverter upgrade on my Class B (Winnebago Solis 59PX). It consisted of new batteries, Victron Inverter, DC o DC charge, Cerbogx w/touch, solar charge controller, smart shunt, a/c easy start and several other things. The work was clean and he did an excellent job at a fair price. I totally recommend CTS. "

Common Questions
How much does a Class B lithium upgrade cost?
It depends on battery size, inverter, solar and charging. Every system is quoted per van after a consultation. Call for a quote.
Can I run my air conditioner on batteries?
Yes, with the right battery bank, inverter and a soft start. We size the system so you know how many hours of AC you’ll get.
Will lithium charge from my van’s alternator?
Yes. We install DC-DC chargers or a second alternator, depending on how much charging you need while driving.
Do you work on factory-installed systems?
Yes. We diagnose and repair factory lithium and alternator systems, and we can upgrade them.
How long does an install take?
Most Class B systems take a few days in the shop. We’ll give you a firm schedule with your quote.
