The Go Power! 200 Watt Wired for Solar Kit Gives Your Pre-Wired RV a Shade-Tolerant 200W Panel and an App-Connected 30A Controller Without Extra Cables
The Go Power! 200 Watt Wired for Solar Kit (WFS-200-PWM) is built for RVs that left the factory pre-wired for solar, with cable already running from a roof port to the controller location. It includes a ShadeTech 200W shade-tolerant solar module, a GP-SB-PWM-30-BT 30 amp PWM controller that connects to the Go Power! Connect app, mounting hardware and a solar controller fuse kit. It skips the 25 foot installation cables a full kit includes, because your RV already has that wiring.
Go Power estimates that 200W of solar puts back about 60Ah a day into a 12V battery on a sunny spring or summer day and about 24Ah in fall and winter. It pairs the kit with a 100Ah lithium or 200Ah AGM battery bank.
Go Power! 200 Watt Wired for Solar Kit Features
Made for RVs Already Wired for Solar
On a pre-wired RV, you only install the panel and the controller. Go Power's kit manual says the controller goes in the predetermined Wired for Solar location, where the solar and battery wires have already been routed, and a Wired for Solar decal marks the spot.
A ShadeTech Module That Keeps Charging in Partial Shade
The ShadeTech 200W module is rated at 9.2 amps. Go Power designed it to keep charging through partial shade, so shade at your campsite doesn't stop it from charging. Each panel has 3.3 feet of cable from its junction box, and the junction box manufacturer rates the box IP67.
A 30A PWM Controller With an LCD and Bluetooth
The GP-SB-PWM-30-BT is a 12 volt, flush-mounted, single-bank PWM controller rated for a continuous solar input of 30 amps. Its backlit LCD shows charging current, battery voltage, state of charge and amp hours charged. Over Bluetooth, the Go Power! Connect app on iOS and Android shows state of charge, battery type, voltage and current, keeps amp hour history and alerts, and lets you change settings.
Lithium and Lead-Acid Charging Profiles
Choose sealed/gel, AGM, flooded, LiFePO4 (lithium) or a custom profile. The controller uses four-stage charging (bulk, absorption, float and equalize) with temperature compensation, and its lithium wake-up feature sends five pulses to restore a LiFePO4 battery whose BMS has shut it off after over-discharge.
Room to Grow to 400 Watts
Go Power says you can add the Overlander-E expansion kit to grow the system to 400 watts on the same 30A controller. The controller accepts up to 600W at 12V, with panels wired in parallel only and their total maximum power current at or below 30 amps.
Real-World Applications
Pre-wired trailers and motorhomes. Finish the solar setup your RV was built for without buying cables you don't need.
Campsites with trees and awnings. The ShadeTech module keeps charging when part of the panel is shaded.
A 12V compressor fridge. Go Power says 200W puts back enough on an average day to run a 12V compressor fridge.
Everyday basics. Go Power estimates the kit handles lights, fans, the water pump and device charging with margin.
Practical Comparison
Wired for Solar Kit Versus a Complete Overlander Kit
The Wired for Solar kit ships only the panel, controller, mounting hardware and fuse kit your pre-wired coach needs. If your RV isn't pre-wired, Go Power points you to a complete Overlander kit, which includes the installation cables.
ShadeTech Module Versus a Standard Panel
Go Power's kit manual notes that shading can greatly reduce a solar system's performance. The ShadeTech module is Go Power's shade-tolerant design, built to maintain charging output through partial shade from trees, awnings and gear.
Buyer Guidance
Confirm Your RV Is Pre-Wired
Look for a solar port or cap on the roof and a controller cut-out or blank plate inside, usually near the entry door or the 12V panel. Your owner's manual can confirm it. Before you install, Go Power says to check that the existing wiring gauge and circuit protection match the controller manual. That means #8 or #10 wire for this 30A controller, wiring of 25 feet or less from the panel to the battery, and a fuse or breaker no larger than 30A on the positive wire within 18 inches of the battery. If that wire isn't fused, install the included fuse kit.
Mount the Panel and Set the Battery Type
Bolt the four L-bracket feet into the four rivet nuts in the panel frame and tighten them to 100 in lbf (11.3 Nm) with a 3/8 inch socket. Mount the panel at least 3 feet from the front edge of the RV, without overhanging the sides, on a surface at least 1/2 inch thick, and seal around each foot. Then set the controller's battery type. A lithium battery must be LiFePO4 with a BMS.
This May Be A Good Fit If
- Your RV came pre-wired for solar
- You often camp under trees or awnings
- Your bank is 100Ah lithium or 200Ah AGM
- You want to check charging from your phone
Common Questions
What Does Wired for Solar Mean?
Many RVs leave the factory with cable already running from a roof port to the controller location. This kit skips the 25 foot installation cables a full kit includes and ships only what a pre-wired coach needs.
Can I Expand It Later?
Yes. Go Power says the Overlander-E expansion kit grows the system to 400 watts on the same 30A controller.
Will It Charge Lithium Batteries?
Yes. The controller has a LiFePO4 profile, and Go Power pairs the kit with a 100Ah lithium or 200Ah AGM battery bank.
What Warranty Does It Carry?
Go Power gives the panel a 25-year limited power output warranty and warrants the GP-SB-PWM-30-BT controller for five years from the date it ships from the factory.
