Welcome back Scott,

The 200 watt panel you need is actually the one you are looking at, the Go Power Overlander Expansion Kit, part # GP76AR. It gives you the 200 watt solar panel without including another controller, so you can pair it with the Go Power PowerTrak 30 amp MPPT Solar Charge Controller, part # GP32QR.

I like going with the MPPT PowerTrak 30 amp controller here because it is able to optimize the power coming from your solar panels instead of using a traditional PWM controller. It works with 12 volt and 24 volt battery banks, has charging profiles for lithium, AGM, gel, and flooded batteries, and gives you some flexibility if you decide to expand your solar setup down the road. That makes the GP76AR panel and GP32QR controller a really nice combination without paying for a controller you already know you do not want.

Are you starting with just this one 200 watt panel, or are you thinking about adding more solar later?

Yes the 200 watt expansion kit works well. I have added two 200 watt Go Power expansion panels to my existing 125 watt panel. I have the Go Power 30 amp controller supplying my two 100 amp hour lithium batteries. I did add 15 amp inline fuses from eTrailer since I have three panels in parallel. Good luck with your project.

@MattI Thanks for sharing your setup, Matt! That’s really helpful real-world feedback. Thanks for sharing your setup, Matt! That’s really helpful real-world feedback. What all are you able to power with your 525 watts of solar?

@HeatherA I can power my 12 volt refrigerator, furnace, water heater, lights, water pump, and usbc chargers for many days with good sunlight. Since I don’t have an inverter, I can’t run 110 systems. I have a on board generator for that or shore power.

@MattI That's awesome Matt. That sounds like a really nice setup for keeping all of your 12V essentials going without having to rely on the generator as much. Being able to go for several days with good sunlight is impressive. Do you do much boondocking with your setup?

Scott - my Flagstaff EPro came with a single 200 W panel, and last year I bought three more of these expansion kits without the MPPT. I then revamped my solar system completely, upgrading my setup to include a Victron inverter, shunt, and MPPT. Later, on a trip, hired Sota Solar in Minneapolis to add a DC to DC charger and two more 100 W panels for a total of 1000 watts. Point being, you can head down the GoPower route with these panels as I did, and just as easily head in another direction and go Victron if you want, and either way, these panels will be compatible and you won’t lose your investment in the panels.

I purchased 200 watt Go Power Overlander Expansion Pack to upgrade my factory installed Go Power panel. I also changed to a Rich MPPT solar controller and added two 100 amp hour lithium batteries. Install is not difficult if are somewhat mechanically inclined. This combo was more than enough for a 2 month trip to Alaska and the Artic ocean. We camped with hookups a total of 4 days on the trip and used them oly because we paid for full hookups.
