Yes. I have a laptop charger about 60W that can feed into the Solar MPPT/Charge Controller. I tried it once it worked. I just found a knife switch in Amazon that should allow me to switch the source. https://www.amazon.com/gp/product/B07V5YYWFV/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1...

Thanks for the link.

Is it ok to add an a/c charge controller to a solar charge controller + lithium battery system? Also is it possible to add a repurposed laptop charger + mppt solar charger to the same? How about a switch to change the source of the existing solar charge controller to the laptop charger? What...

Thanks. I took a look at the wiring today and this confirms my findings. I do not have access to all the wiring so to do what you do is a much bigger job. so here is what I plan to do. The existing battery positive goes to a switch. On the other side of the switch are 3 wires. One thicker one...

I guess it doesn't matter since when the vehicle is not running the 7 pin is disconnected anyways.

But you're saying the battery is drained when TV is not running? I am not concerned the LFP not getting charged just don't want the battery and alternator killing each other.

Just don't want the complexity and I will not run a dedicated wire from the alternator anyway. So would rather spend money on getting solar if there is a need.

My camper has the WFCO 8735 converter. The 7 pin is connected to the camper for trickle charging and signal and brakes. Since I will be replacing the Lead Acid battery with Li, I want to disconnect the 7 pin from trickle charging the battery. I do not want to install a DC/DC charge, just want to...

These all in ones are nice and definitely good deals for the build in transfer switch but are overkills for my setup. I don't need an inverter so it's a matter of shore charger + solar charger for about $300 from victron. If I do need AC I will just run a small one which I already have for my...

Maybe the voltage measured is not that accurate. 0.1V is probably within the margin of error. Current will go from high voltage to low voltage.

Thanks!

Can I hook up solar power charging (for example Renogy solar kit, MPPT) and shore power charger (for example Progressive Dynamics converter charger) at the same time? I have a small trailer with factory installed WFCO converter and DC distribution panel. Do not need inverter for now. The plan...

@A.Justice this is exactly what I need, for this small backup system. I have two pumps 24V, 50W together and the router is 12V 17W running. I will get the 12V version and step up to 24V. Then I would be able to use the same battery in my teardrop camper as well. Thanks!

Lots of good points. Thank you. The reef tank would consume about 60 Watts then the power is out. The lights and heaters will not be running. If I budget for 20 hours of run time then it will take 1200 Watt-Hours. The growatts is probably too big for me. This will work for me also, right...

I am new here but have been watching a lot of battery videos. Want to get my hands wet by setting up a small backup system, UPS. But to this day I have not been able to find a design for what I think a simple need. Maybe I am making everything too complicated. I have a reef tank and all the...
