Thanks. I know the BT option can report info back to the phone app but I would like to still install the battery monitor and shunt. Just to have a quick visualization of the battery status. Somehow 70% capacity speaks to me better than 125Wh consumed. I guess if I use the load terminals on the...

I have one 100W solar panel with Victron MPPT 75/10 solar controller (with Bluetooth). This system is in my car (well, panel is on the roof of course). The load on the system is two USB ports plus a 12V cigarette socket where a refrigerator is plugged in. According to the SCC specs, it can...

I am building a small one solar panel system in my car (100W solar panel, SCC and 50Ah battery). I just received the Epever MPPT SCC (10A 12/24V). The SCC has input for the solar panel, output to the battery and also third set of sockets for load (a bulb icon). So here are my questions: 1. Is...

Thank you!

I am building simple one solar panel system to install in my car. The goal is to periodically run a refrigerator during the weekends. Here is a diagram that I have come up with after doing some research. The solar panel is 100W with the following specs: Controller is Epever 10A model Tracer...

Not really. I have inquired with a manufacturer and my power station cannot be charged via solar and used at the same time. That's what prompted the whole solar project. If I could just add a solar panel to my power station, I would be all set. As to mounting the panel, I got that covered. I...

A weekend outing is my goal. Usually, me and my kids, we go for one full day (6am till 6pm). The fridge is portable so it doesn't stay in the car unless we prepare for a daytrip. All I need is to have enough battery left in case we stay overnight or for those super hot summer days or when kids...

Maybe when you look at the raw numbers, that's true. But in my case, with the 50Ah power station I have, I cool all the stuff at home (in the refrigerator), then set the car fridge to 36F, drive 1-2 hours and leave the car for 8 hours or more in the sun. Two weeks ago, the battery was down to...

I was looking at the DC to DC chargers to which I can also hookup solar panels. Unfortunately, the price $200+ is a bit much for the simple system I want to build. Also, we usually drive up to 2 hours one way and have the car parked for the rest of the day. For a longer drives, I can always...

I have a fridge similar to the Dometic mentioned by Mike. The idea of a controller that can take input from solar as well as car's alternator is great. It is just the price that holds me back. I was initially looking for an inexpensive one panel system and now I am adding/upgrading to the...

The fridge is a 12V portable one. When on, it draws about 46W of power. My current power station has about 50Ah capacity and works fine. The reason for the solar panel is (if I can charge and discharge at the same time) that the panel will maintain the battery and the time I can use the fridge...

Thanks again guys. Any recommendations on a SCC that would work better than the cheap PWM Renogy? If the MPPT is that much better, I could spend up to $100 on one. The only requirement would be small size. I can't fit anything like Renogy Rover which is 9" tall. The max I could fit is up to 6"...

Thanks for all the replies. I watched the video and honestly, unless I am missing something, I didn't get an impression that MPPT is that much better than PWM. Besides the issues with wire terminals and ease of programming (which I probably won't do for 1 panel and 1 battery system), the...

I want to build a small (1 panel) solar system for my car. The goal is to run a portable refrigerator. I am currently using a power station but while it has a built in MPPT controller that supports solar charging, it cannot charge and discharge at the same time. So here is what I think I need...

Thank you for the explanation. All makes sense now.

I read some threads regarding charging and discharging the battery at the same time but I am still a bit confused. In a super simple setup with 100W solar panel, PWM controller, battery and a load (i.e. LED lights), can the solar panel charge at the same time when the LED lights are connected...

I have contacted the BigBlue Tech that makes the power station and according to them, I cannot charge and use the battery at the same time. Pass thru is available only when using 120V or 12V chargers. I guess the station can somehow determine when the voltage coming in is from solar or other...

Thanks Mike. I am using this power station for about a year now and while never charged via solar, I have charged it thru 120V outlet and also via 12V car outlet. In both cases, I left the charging cable connected for days after the power station was fully charged. Nothing bad happened. Not...

Anybody with an actual solution or thoughts?

I have a BigBlue CellPowa 500 power station which I use in the car for day trips or camping. I usually just have a small refrigerator connected to it to keep the food and drinks cold in the summer. The power station has a built-in ability to charge via a solar panel so I would like to install...
