Renogy RV Solution Go Far: Our 3.8 kWh Travel Trailer Install, Tested

We wanted real off-grid power in the travel trailer, without piecing a system together part by part. So we installed the Renogy RV Solution "Go Far" kit: a 3.84 kWh lithium battery, a 2000 W inverter and a 195 W solar panel on the roof. Here's how we built it, what we ran on it, and our verdict.

In brief

• Capacity: 3.84 kWh (12 V 300 Ah LiFePO4 battery)
• Inverter: 2000 W pure sine wave, with transfer switch
• Charging: 195 W ShadowFlux panel + the vehicle's alternator, through a 50 A DC-DC charger with MPPT
• Our verdict: we recommend it

What's in the Go Far kit

• Battery: Mini 12 V 300 Ah LiFePO4, 3,840 Wh
• Inverter: 12 V 2000 W, pure sine wave, built-in transfer switch
• Charger: 50 A DC-DC with MPPT (alternator and solar)
• Solar panel: 195 W ShadowFlux N-Type, anti-shading
• Accessories: 300 A bus bars, 350 A disconnects, Bluetooth shunt, BT-2 module, cables, fuses, hardware

The parts are numbered and come with a wiring map and guided videos. The cable between the vehicle's starter battery and the system isn't included, since its length depends on each vehicle.

The install: everything on a board first

Our best advice: mount everything on a sheet of plywood before you drill a single hole in the trailer. Batteries, inverter, charger, disconnects and bus bar all fit on one board. You check the wiring, fix what's wrong, and only then fasten it down for good.

That way the whole system fits in a single compartment. The inverter switches on from a wall console, without opening the compartment. The BT-2 Bluetooth module plugs into the charger: it shows the charger's status, not the battery's charge, which the shunt tracks.

The test in the trailer

With the inverter on, we ran our everyday devices: the water pump, the coffee maker, the TV, the roof fan, the chargers, the drone batteries and the laptop. The coffee maker starts without a hitch: that's where the pure sine wave matters, because motors and sensitive electronics handle it better than a modified sine wave.

Charging: sun and alternator

According to Renogy, the 195 W panel produces about 1 kWh a day with 5 peak sun hours. Combining solar and the alternator while driving, the system can recover about 2 kWh a day. You can add panels up to 585 W (three 195 W panels) and parallel up to 8 batteries.

Price

The Go Far 3.8 kWh kit is listed at CA$2,749.99 regular, and CA$2,499.99 on sale as of October 1, 2026. The Go Further 7.6 kWh version is CA$4,069.99 (CA$3,699.99 on sale).

Our verdict: we recommend it

The Go Far kit is complete, clean and designed for a DIY install. It fits in a single compartment and runs everything we plugged in, coffee maker included. For weekends and holidays in a trailer, it's the right capacity; to live off the grid for long stretches, look at the 7.6 kWh version.

FAQ

Can you install the kit yourself? Renogy designs it for owner installation, with numbered parts, a wiring map and videos. If you're unsure about the wiring, have a professional check it before you power it up.

Can you add more solar panels? Yes, up to 585 W in total, or three 195 W panels, with the required connectors.

Does the BT-2 module show the battery's charge? No. It plugs into the charger and only shows its status; the battery's charge is tracked with the shunt.

Does the system work on campground power? Yes. The inverter has a pass-through function: when the trailer is plugged in, campground power runs the big appliances directly, like the rooftop air conditioner.
