Solar Power

Cupie · Cupie

I have read that AGM batteries in particular are susceptible to damage by overcharging. The use of Smart chargers address this but how do you avoid this issue when charging from your solar panels and from your vehicle? In my case I use a DC to DC charger to connect my solar and vehicle alternator, which I...

Has anyone purchased from these guys please. They are offering a 130watt panel for a really good price. Claims to be " German Certified" and fits my available space on roof rack, plus I get extra 30 watts on next best deal. They say " no middleman". cheers and thanks Craig

My solar regulator is a PWM and doesn't show state of charge. Without having to change the regulator, what are my options to be able to show SOC of my 2 batteries which are 2 x 120 amp agm connected in parallel - pos to pos. Don't really require all the bells and whistles, (already have volt meter on batteri...

Reassessing power usage. Anyone know the power usage of the Wineguard amplified wind up/down antennas used on many current vans? Been searching online and 12 volts is the only thing I can see listed. Cheers, John.

After reading what Jaahn Aus Kiwi and others have said about moveing the voltage regulator,from the portable solar panels to closer to the battery's,it makes a lot of sense so I had a serious look at what's involved today . At the moment the long cable is connecting the panels to the battery. when the r...

Hi all I have bought 3 solar panels for van roof 2x 200w mono, and 1x 170w panels. the reason is these are the only ones I can fit due to hatches etc. I have 2 deep cycle 100ah calcium batteries in good order and intend to a 50amp mppt controller and a 3000/6000w pure sinewave inverter. We would like to fr...

I have a 220 watt panel to fit to my pop top roof. The roof is Aluminum sheet that is fixed and siliconed all around the perimeter. I am concerned that if I Sikaflex glue the Aluminum angle to the roof the solar panel may cause fatigue in the roof sheet as the panel is subjected to wind and other loads. Does an...

Hi there. In very simple terms can some body explain why/if panel output is effected if mixing panels. Eg: 120watt with 80watt. Thanks in advance. Kezngaz.

would anyone know how to calculate how much 12volt power we would use over night when we arrive at a sight with a full battery load lets say 13 volts on the meter ours is in the cupboard,and the same meter is reading 12 volts in the morning,that means we have used one volt over night right? thats how I though...

G'Day I am going to install a new MPPT controller and the recommendation is to change from parallel to series. From the pwm picture the positive and negative leads from two panels are wired into the same ports on the controller, to make it series do I join one +ve to -ve ( in an isolated block) and then wi...
