I have 4 linked solar panels giving 60watts output.
A 7.5 amp voltage regulator.
A 400 watt 12volt input to 120 volt output inverter
Two 12 volt deep cycle batteries.
The inverted output runs my TV , dish and 13watt lamp very well.
Can I charge the batteries during the day, while running the TV and Dish with the inverter?
Can you safely charge batteries with a solar panel while there is an output load applied to them without damaging any equipment?

I got started with a solar charger to keep my parents car battery up. It didn’t have a charge controller and when I started the car it felt like the starter motor had too much power! The car engine started quick but I didn’t know about charge controllers.
I wouldn’t use a solar charger without one now!

Hi, I am going camping for 2 weeks and need to power my CPAP machine (used at night to help me breath) with a battery. I will have my hybrid car with me. I was wondering what the best way to recharge the battery would be. Would the car be enough? I don’t want to risk damaging or depleting the battery in the car. If I used a solar panel what type would be best. How would I best set up this system?

I have 2 12v batteries in a series to run my trolling motor. I have 2 solar panels I purchased to help recharge the batteries. When recharging, what posts do I attach to. I would assume the POS of one battery and the NEG of the other?
