To charge two batteries from one solar panel, you need two solar charge controllers. My new PWM5 controller has been specifically designed to be used in this configuration. Both batteries are individually monitored and controlled to ensure optimum charge rate and voltage. This is a common configuration on boats. One battery is used to start the engine and the other is used for navigation electronics or TV/fridge.

What size solar panel would I need to charge two 12v batteries at once
im looking for this video for a week, is this really work? does it still working today? please help… thank you so much…
you should make a video of this with two battery banks that have their own controllers built in, such as a jackery. Many people have multiple units
Rr
can we use one solar panel to charge the two batteries with switching over them sir [ I mean that we can moniter the status of both batteries and which is low in power only can charge by the pannel and when it charge higher than the second one then the second one is going to charge ] can you help me with this sir????
Can you use any type controller and what amp please
What size panel are you using?
How do I split the solar wires to go to two different charge contollers? Thanks this really hepled
hi. tryed you web site, but can't get on it for some reason, as i am interested in this pwm 5 controller, and would like to buy 2 of them. tell how please thankyou stephen
Didn't work for me, got a AGM and lead acid, agm charges fine on mppt while the lead acid is overcharging to about 16v while charge controller everything is below 12v because of this but no dice.
Time to call a mechanic electrician.
Thanks for the informative video. I'm trying to get some advice on how to use Solar panels, to charge my deep cycle Electric trolling motor batteries, three 12 Volt batteries, all wired in series, to supply the necessary 36 Volts to the motor. The controllers you are showing in the video, are they simply diodes to isolate the batteries from each other?
Hi good video
Can I buy these direct
it is safe ???? im ended up buying 1 solar panel for another charge controller. i have 2 batts now and 2 controller and 1 solar
excellent thanks. I need to keep the battery from my electric boat charged along with my solar powered sleepout but just use the one solar panel on the roof of my sleepout. thanks.
batteries need to be charged as high as 14.7 volts how do i achieve this
Just watching in 2018 😀
Can solar charge the car battery and use it at the same time? Is it safe?
