How to Install an RV Solar Kit | Canada Comprehensive Guide

You've made the switch to solar. Great choice! But now the box is sitting in your garage, and you're wondering: how do I actually install a solar kit?

Don't worry. This guide is written for real people, not just engineers. Whether you have a motorhome, a camper van, a tiny home, or even a shed, you'll learn how to install a solar panel kit safely and get it working right the first time.

We'll use the Renogy 7.6kWh The Go Further Solution as our example, but the same steps apply to most solar kits. Let's get started!

What to Do When You Receive Your Solar Kit

Before you grab any tools, take a few minutes to unpack everything carefully.

Check off each component

Your solar kit should include:

• 2 × 200W Shadowflux Solar Panels
• 2 × 300Ah Mini Size LiFePO4 Batteries
• 1 × 50A DC-DC MPPT Battery Charger
• 1 × 3000W Pure Sine Wave Inverter
• Battery shunt, inverter switch, cables, fuses, and busbar

Inspect for damage

Look closely at the solar panels, make sure there are no cracks, chips, or scratches. Then move on to the battery cases and check for dents or leaks. Make sure all cables have clean, undamaged connectors.

If you find anything missing or broken, take a photo of the issue and contact Renogy support right away. They'll help you sort it out quickly.

Solar Kit Installation Preparation

If you want to learn how to install a solar panel kit the right way, start with the wiring diagram. Every quality solar kit includes one on its product page. You'll see a simple flow:

Tools you'll likely need

• Drill and drill bits
• Screwdrivers (Phillips and flathead)
• Wrench set
• Wire strippers / cutter
• Ground Fault Circuit Interrupter (GFCI)
• MS Adhesive and MS Applicator Gun
• Cables

⚠️ Safety first

• Wear insulated gloves and safety glasses
• Use insulated tools
• Disconnect any existing battery before you start
• Work in dry weather

Step-by-Step Solar Kit Installation

We'll follow the manual's order. Don't skip steps-the sequence matters.

1. Mount the solar panels

• Use the Z brackets (included).
• Measure and mark positions on your RV roof, avoid vents, AC units, and shadows.
• Pre-drill small holes, add sealant, then screw the brackets down.
• Attach the solar panels to the brackets.

2. Install the solar entry gland

• Drill a hole for the cables (use the gland as a template).
• Run the adapter cables through the hole, then seal it with the included MS adhesive.
• Do not move the entry gland before the MS adhesive is fully dry.

3. Ground the combiner box

You need to prepare a 10 AWG grounding cable by yourself. Then connect the combiner box to your vehicle chassis or a proper ground rod.

4. Connect the batteries to the combiner box

• Connect the batteries in parallel.
• Connect positive to positive, negative to negative.
• The shielded wire and B+ wire are inside the battery monitor packaging box. Don't lose them.

5. Connect the charge controller to the combiner box

• Install the cables and MRBF fuse on the combiner box.
• Remember to connect the negative first.

6. Wire the solar panels

• Your three panels are connected in parallel using the M branch adapters.
• Add a 15A fuse on each positive panel wire before merging them.
• Run the combined positive and negative cables to the charge controller.

7. Install the Bluetooth module and ONE Core

Bluetooth module: plug it directly into the charge controller's RS485 port. When it is finished, the power light will turn on.

ONE Core: open the ONE Core, connect it to the combiner box using the power cable from its box. It gives you a central display and remote control.

8. Ground the inverter

• Prepare 10 AWG cables ground wire by yourself.
• Use the wire to ground the inverter to your vehicle frame. Insert into the ground when parked, and remove when driving. This is important for safety.

9. Connect inverter to the combiner box

• Finally, install the cables and 350A MRBF fuse for the combiner box circuit and the inverter circuit. Remember to connect the negative first.
• Then install the GFCI (Ground Fault Circuit Interrupter) on the inverter.
• Double-check that all nuts are tight.

10. Power up!

Turn on the charge controller. Make sure the inverter is off, then turn on the battery disconnect. Check the charge controller display, it should show battery voltage. Then expose the solar panels to sunlight. The controller should start showing charging current. Finally, turn on the inverter and test a small AC load.

Common Mistakes of Solar Kit Installation

Mistake	Why it's bad	Fix
Connecting solar panels before battery	Can fry the charge controller	Always connect battery first, then panels
Loose cable connections	Overheating, voltage drop	Use a wrench – tug each cable gently
Ignoring shading on one panel	Whole array output drops	Relocate panels or trim nearby objects
Forgetting to ground the inverter	Risk of electric shock	Add a 10 AWG ground wire to chassis
Wrong battery type setting in controller	Batteries never fully charge	Use the app or screen to set “Lithium”

What to Do After Installing Your Solar Kit

Do

• Clean the solar panels with water and a soft cloth every few months.
• Check roof seals and the entry gland for cracks twice a year.
• Use the Renogy app to monitor battery state of charge and history.

Don't

• Don't add extra solar panels without checking the charge controller's max voltage.
• Don't disconnect the battery while the sun is shining on the panels – it can cause a voltage spike.
• Don't run heavy AC appliances (like an air conditioner) unless you know your 3000W inverter can handle the surge.
