How Do I Install My System?

If you’re installing a solar panel kit, we typically recommend following this process to ensure a seamless and safe installation.

1. Mount the Solar Panels

Use the included Z-brackets to secure the two 200W solar panels to your RV roof.

Measure and mark positions, avoiding vents, AC units, and shaded areas
Pre-drill pilot holes, apply sealant, then screw down the brackets
Attach panels to the brackets securely

2. Drill the Wire Entry Hole

If your RV roof doesn't already have a pre-drilled wire hole:

Use the entry gland as a template to mark the hole location
Drill carefully through the roof
Run the adapter cables through the hole
Seal thoroughly with the included MS adhesive
Important: Wait for the adhesive to fully cure before moving or disturbing the gland

3. Connect the Battery Bank to the Busbars

This is the foundation of your electrical system:

Negative connections:

Connect both battery negative terminals together
Connect battery B's negative terminal to the shunt's B− terminal
Connect the shunt's P− terminal to the 300A black busbar
Attach the shunt's T1 temperature sensor to the battery casing

Positive connections:

Connect both battery positive terminals together
Run from battery A's positive terminal → 400A ANL fuse → 350A battery switch → 300A red busbar
Connect the shunt's B1 terminal to battery A's positive terminal

4. Connect the Battery Charger to the Busbars

Connect the charger's NEG− terminal to the 300A black busbar
Connect the charger's OUT+ terminal → 80A ANL fuse → 300A red busbar

5. Connect the Battery Charger to the RV Starter Battery

This enables bidirectional charging while driving:

Run a user-supplied cable from the starter battery negative to the 300A black busbar
Connect the charger's ALT+ terminal → 80A ANL fuse → starter battery positive
Connect the shunt's B2 terminal to the starter battery positive

For smart alternators: Install the included IGN signal wire from the charger's Ignition port to the smart alternator's IGN terminal or the vehicle's ignition fuse box.

6. Connect the Solar Panels to the Charger

⚠️ Critical safety step: Cover the solar panels with an opaque material before making connections. Connect the battery first, then solar panels—never reverse this order.

Connect both panel positives to the positive Y-branch connector
Connect both panel negatives to the negative Y-branch connector
Route the negative Y-branch to the 300A black busbar
Route the positive Y-branch → 30A solar fuse → charger's PV+ terminal

7. Install the Bluetooth Module

Plug the BT‑2 Bluetooth module into the battery charger's RS485 port. This allows you to monitor charger status through the Renogy App.

8. Ground the Inverter

Prepare a 10 AWG grounding cable (user-supplied). Connect one end to the inverter's grounding terminal and the other end to the vehicle's metal frame. Scrape off any paint to ensure good conductivity.

9. Install the Remote Switch

⚠️ Safety first: Before wiring, set the inverter's ON/OFF/REM switch to the OFF position.

Set the switch to the REM position
Insert one end of the wired remote cable into the remote switch
Insert the other end into the inverter's REMOTE port

10. Connect the Inverter to the Busbars

Connect the inverter's DC− negative terminal to the 300A black busbar
Connect the inverter's DC+ positive terminal → 400A ANL fuse → 350A inverter switch → 300A red busbar

11. Final Power‑Up Sequence

Follow this exact sequence to avoid damage:

Before turning anything on, double-check all connections are secure
Cover the solar panels' light-facing surface
Turn on the battery switch first
Remove the solar panel covers
Turn on the inverter switch
Test a small AC load to verify operation

How Do I Stay Safe While Installing Solar Panels?

Working with solar equipment can be dangerous if you don’t know what you’re doing. Here’s some tips to keep in mind to keep yourself safe.

Stay anchored: One of the biggest risks in installing solar is the potential to fall off your roof. We recommend using a roof anchor tool, which can save your life if you happen to lose your footing. Anchors can be installed temporarily while you install panels, or you might want to permanently install them to make it easy to safely access your panels in the future.
Double check your equipment for damage: We at Renogy take great care in packaging and shipping of our materials, but sometimes equipment can get damaged while in transit. So it’s important to always visibly check all of your equipment when you receive it. Damaged components can lead to lower performing equipment, or could even cause fires or other shorts.
Do not work alone: Use the buddy system when you’re installing solar on your home. It’s always helpful to have a second pair of eyes and hands to help you. It’s also important for your safety, in case something was to happen and you needed emergency assistance.
Don’t work in the rain: Roofs can get slippery very quickly when it starts to rain. It’s always best to wait until the weather is dry.
Insulate yourself to protect yourself from electric shock: If you are not careful, direct current has the ability to give you a serious shock. Always adhere to all codes, regulations, and manufacturer’s guidelines when installing a solar system. Don’t wear any conductive items, such as jewelry and watches. We also recommend always using insulated tools and rubber gloves.
When in doubt, consult an expert: Last, but not least, if you’re uncomfortable or unsure about anything involved in the installation process, we recommend talking with or hiring an expert to help you get the job done safely.

Can a Short Circuit Damage My Solar Panels?

This is where fuses and circuit breakers come in. Fuses and circuit breakers are used to protect devices from becoming damaged if there is a short circuit. They also prevent your wiring from getting too hot and catching fire. If a short develops in your solar inverter, a fuse between it and the battery will prevent a possible explosion of the battery. It will cut the circuit fast enough to prevent the wires from catching fire or getting dangerously hot. In this case, the battery, wires, and AC/DC inverter will be safely disabled by the fuse.

Conclusion

Although it’s never been easier to go the DIY route with solar, there are still some crucial safety considerations to keep in mind during the installation process. Always be sure to follow the manufacturer’s instructions on all your equipment and heed our above advice, from not working alone to insulating yourself to stay protected from shock. Do that and you’ll ensure a safe and seamless installation process.
