Why M-Oceans for RV Power

Marine-Grade Engineering for Your RV

We built our reputation designing battery and solar systems for boats — where reliability isn't a preference, it's a safety requirement. Salt water, vibration, temperature extremes, limited space. Marine environments punish sloppy electrical work fast.

RV power systems face the same challenges. Temperature swings between a July afternoon in the Okanagan and an October night in Algonquin Park. Vibration from thousands of kilometres of road. Limited roof space for solar. A growing list of appliances that all draw from the same battery bank.

The components we use for RV systems are the same ones we trust on the water — Victron inverter-chargers, Epoch and ReLion LiFePO4 batteries, SmartSolar MPPT controllers. The design approach is the same too: size the system to your actual usage, match components that communicate with each other, and build in enough headroom that you're not running on the edge.

Note: We're currently expanding our RV-specific product lineup and pre-configured kits. In the meantime, we're designing custom RV systems for customers across Canada — starting with a conversation about how you actually use your rig.

Your RV. Your Power Needs.

The right solar and battery setup depends on how you travel. A weekend warrior plugged into campground power has different needs than a full-timer boondocking in Northern Ontario. Here's how we think about RV power systems.

  • Weekend Campground

    SHORE POWER AVAILABLE

    You camp at serviced campgrounds most of the time, but want backup power for the occasional night without hookups — or just want to stop worrying about your battery dying overnight.

    TYPICAL NEED: A lithium battery upgrade (replacing factory lead-acid) and a quality converter-charger. Solar optional but not critical.

    WHAT CHANGES: Faster charging from shore power, more usable overnight capacity, and a battery that actually lasts more than two seasons.

  • Extended Boondocking

    OFF-GRID FOR DAYS

    You prefer provincial parks, Crown Land, or backcountry spots with no hookups. You need enough power to run a fridge, lights, water pump, and charge devices for 3–7 days without plugging in.

    TYPICAL NEED: 200–400Ah lithium battery bank, 200–400W roof-mount solar, MPPT charge controller, and a small inverter for AC loads.

    WHAT CHANGES: Genuine energy independence. You stop planning trips around power availability and start choosing campsites for the view.

  • Full-Time RV Living

    YOUR RV IS YOUR HOME

    You live on the road full-time or for extended seasons. You run a full household — cooking, heating, working remotely, streaming, laundry. Power isn't a nice-to-have, it's infrastructure.

    TYPICAL NEED: Large lithium bank (400Ah+), 400W+ solar array, inverter-charger (Victron MultiPlus or Quattro), Cerbo GX monitoring, alternator charging via DC-DC charger.

    WHAT CHANGES: You stop compromising. Run the air conditioner, use the microwave, work from your laptop all day — and monitor everything from your phone.

Components of an RV Solar & Battery System

An RV power system works on the same principles as a marine setup — store energy, manage it smartly, and protect your equipment. Here's what a complete RV system typically includes.

  • Gray Epoch lithium-ion battery on a white background

    LiFePO4 Battery Bank

     Drop-in replacements for your factory lead-acid. Lighter, more capacity, charges faster, lasts 10x longer. 12V for most RVs, 24V or 48V for larger coaches.

  • Victron BlueSolar Monocrystalline Panels

    Roof-Mount Solar Panels

    Rigid or flexible panels mounted to your RV roof. Sized based on your daily power consumption and available roof space. Monocrystalline panels give the best output per square foot.

  • Victron Energy solar charge controller on a white background

    MPPT Solar Charge Controller

    Sits between your panels and batteries, maximizing energy harvest and protecting against overcharge. Victron SmartSolar controllers are our standard — Bluetooth-enabled and programmable

  • Blue Victron energy MultiPlus-II GX power station on a white background

    Inverter-Charger

    Converts DC battery power to 120V AC for appliances AND charges your batteries from shore power or a generator. The Victron MultiPlus handles both in one unit — the workhorse of any serious RV electrical system.

  • Monitoring & Wiring

    Battery monitor (Victron SmartShunt), proper fusing, circuit breakers, and marine-grade wiring. For larger systems, a Cerbo GX gives you remote monitoring through Victron's VRM portal.

Built for Canadian RV Seasons

Cold-Weather Performance

Canadian camping season stretches from April to October in most provinces — and shoulder-season nights can drop below freezing. LiFePO4 batteries with low-temperature cutoff protection are essential. For four-season RV-ers or anyone storing their rig in an unheated garage, self-heating battery models from Epoch are worth the investment — they warm internally before accepting charge, so your system works even when temperatures dip.

Winter Storage

Charge lithium batteries to 50–60%, disconnect, and store. They self-discharge at less than 2% per month — no trickle charger needed. For lead-acid holdouts, this alone is a reason to switch: no more checking water levels, no more sulfation worries, no more spring surprises.

RV Solar & Battery FAQs


Can I add solar to my RV myself?

A basic lithium battery upgrade and small solar setup (1–2 panels, charge controller) is manageable for a handy DIYer with basic electrical skills. Larger systems with inverter-chargers, multi-panel arrays, and alternator charging get more complex — that's where a proper system design and wiring diagram save you from expensive mistakes. We provide detailed documentation with every system quote, whether you're doing the install yourself or handing it to a shop.

How much solar do I need on my RV?

It depends entirely on what you run and how long you're off-grid. A rough rule: 200W of panels and 200Ah of lithium battery capacity will comfortably run lights, a fridge, water pump, and device charging for 2–3 days of boondocking in summer. Add air conditioning, an induction cooktop, or a residential fridge and the numbers go up significantly. We size every system based on your specific appliance list — not guesswork.

Should I replace my RV's lead-acid batteries with lithium?

In almost every case, yes. A 100Ah lithium battery delivers more usable power than a 200Ah lead-acid at half the weight. It charges faster, lasts 10x longer, and requires zero maintenance. The only thing you need is a charger or converter with a lithium charging profile — most modern RV converters have one, and upgrading an older one is straightforward.

Will a lithium battery upgrade work with my existing RV electrical system?

For a basic 12V drop-in swap (replacing your house batteries), usually yes. Your existing wiring, fuse panel, and 12V appliances don't need to change. You will need to confirm your converter-charger has a lithium charging profile — if it doesn't, a charger upgrade is part of the project. For larger upgrades involving solar, an inverter, or alternator charging, the system design gets more involved and benefits from proper planning.

What brands do you use for RV systems?

The same ones we trust for marine installations. Victron Energy for inverter-chargers, MPPT controllers, battery monitors, and system management. Epoch and ReLion for LiFePO4 batteries. These aren't the cheapest components on the market — they're the ones we'd put in our own rigs. Victron's ecosystem is particularly valuable because every component talks to every other component, giving you a single monitoring interface for the whole system.

Do you ship RV components across Canada?

Yes. All battery and component orders ship free across Canada. For customers in the GTA, we also offer local pickup and installation support at our Scarborough location. For everyone else, we include detailed system diagrams and installation documentation with every order.
