ExpertPower 200W 12V Solar Power Kit | 12V 20Ah LiFePO4 Lithium Battery | 200W Mono Rigid Solar Panels, 20A MPPT Solar Charge Controller | RV, Trailer, Camper, Marine, Off Grid, Solar Projects

Included: 2 x 100W panels, BT-1 module, 20 amp MPPT charge controller, panel mounting brackets, screws/bolts, 6’ #12 AWD controller to batteries, 10’ #12 AWG wire from panels to control, Y-connect for parallel panel connection if desired. (Note: I called Expert Power and substituted 20’ of #10 AWG for 10’ of #12 AWG and used for connecting panels to controller and controller to batteries. EP assessed a small extra charge for wire upgrade.)Other materials: 5’ x 1” 3M VHB tape, 5’ x 2” Eternabond roof seal tape, 1 tube Sikaflex const. adhesive, rubbing alcohol, 220 grit sandpaper, wire mounting clamps, UV zip ties, flexible wire channel, 7/8” OD flexible conduit, 2-wire roof clamshell, 2 x 30 amp in-line resettable breakers.Installed on 1999 Roadtrek 190P with two coach batteries. I did the install in phases:Phase 1: Plan and draw out configuration for entire system and where to mount panels, controller, breakers, wiring runs between controller and batteries, and controller to panels. Sketch out and mark panel locations on roof. Thoroughly wash roof area with reasonably strong detergent to get all dirt, grime, wax and any mold off roof mounting surface prior to starting.Phase 2: Install controller in preferred location (I used a rear-facing bulkhead panel on driver’s side) and ran wires through the cabinet and behind insulation down to battery compartment (I added a 2nd house battery previously) and connected controller minus (-) wire to my negative terminal block, and the controller plus (+) wire to my 4-position battery switch output terminal (Off, #1, #2, Both). The switch determines which one or both batteries (or neither) will get charged.Phase 3: Carefully put a 7/8” hole in the roof in the exact location you want. I used a clamshell with 2 gland nuts for the AWG wire. Make sure location will not interfere with solar panel location and that the wires will enter the van exactly where you want (I came down the interior side of a cabinet, running my 7/8” flexible conduit up thru the roof with ~1/4 inch protrusion continuing down thru cabinet to run solar panels to controller wires).Phase 4: Bolt the brackets on the panels and dry locate on roof of van. You will likely have to bend the brackets a bit depending on the shape of you roof. I bent the brackets before bolting to the panels to avoid excess stress. Double check panel fit on the roof with brackets attached by placing on roof before “final” location. Use marker to outline bracket and clamshell (if used) locations on roof. When ready, clean brackets with rubbing alcohol, I also used just a bit of 220 sand paper on bracket bottoms. Put the sticky part of the VHB tape on the bracket feet in preparation for roof mount.Phase 5: I lightly used 220 sand paper followed by alcohol wipe to clean the roof surface where the brackets and VHB will be mounted. When all set, locate panels 1 at a time in proper location. Tilt up about 70 degree and remove the protector film on the VHB tape and carefully lower panel into position. Firmly push on the brackets to seat the bracket and tape (it really sticks!). After a day, I sealed around bracket edges with Sikaflex to help keep out weather (I filled the two unused bracket bolt-holes too). After several days I covered the feet of the brackets with Eternabond tape to further keep out weather and moisture (could be OCD on my part but what the heck).So far, the ExpertPower kit is performing great. The BT-1 module would only work with the old version Renogy BT app on my android phone (not the DC Home version) and does not allow for parameter changes. Your result may be different.

I installed this on my Jayco Eagle HT. Very easy to install. I had a prewired system so I was able to use my 8 gauge wiring. I plan on expanding by one more panel in the future. I understand the system can handle 3 100 watt panels. It is a good quality product and I would recommend it to anyone that’s looking for a small starter solar system.

I like the kit. Easy to install. The weakest point is the charge controller. Not user friendly. Especially the app. I wonder if other apps can also work with this controller?It always indicates my battery is at 100% even after having a 5 watt load on it overnight. Sometimes it works, sometimes it doesn't. A decent app that works with this would change this to five stars.

Can't find the app for the Bluetooth module :(

Working great

Finally got around to installing. Install was straight forward as the trailer was "solar ready" however don't believe the hype about wires being marked. Was able to find them and install took about 3 hours. Result is that they work as expected. Will be adding more panels after I verify system capabilities. Parts all were excellent appearing quality. Would like to see an option for cable retention but it was so minor and the solution was simple.

This is an awesome system at a very affordable price. It does help knowing some about solar or having some one who does

Two 100ah batteries and a 12v ton120v 5000w inverter and I can run my 12” chop saw and my compressor simultaneously no problem for my off grid build
