There as been no issues to date and work very well charging a 120amp battery in a few hrs in the morning and on a float charge the rest of the day My question is looking on this forum no...

Hi, I have just purchased a Kings 120w Solar Blanket after reviewing the specs on the web site. However I was surprised to see in the user manual, when opening the blanket after purchase, that the solar blanket and MPPT regulator are not to be used to charge Lithium ion batteries. Stating that the MPPT c...

Hi there! I dont understand anything of energy, let alone solar energy. I got a guy to install it on my van and it is not working. If somebody can give me some advice/clarification/etc, I will be very grateful. This is my equipment and what I would like very much to use it for: 1 DC-12V-140AHX Giant Pow...

Since I have 2 Victron MPPT controllers & 6 solar panels set up as 2 panels in series then in 3 sets. I connected 4 x 26AH & 80AH & 85AH batteries together. Both controllers I tested separately with 120watts of panels. In summer I can easily get 125watts out of the panels & squeezin...

I'm looking to buy a couple of solar panels around 100W each; looking at the specs of the two types I cannot see a lot of difference but as mono are about 50% more expensive than ploy I assume there is a difference and guess that it is in output for given illumination. Your opinions and comments please peop...

We have a couple of solid, hinged solar panels that have worked really well in the past. After a long break due Covid we recently went away with friends and had some problems with the electronics generally. During investigation my friend put his multimeter on the panels and said they weren't working (...

The solar system is 4x12v/200w fixed rooftop solar panels in parallel array feeding 2x150ah AGM batteries. I am also able to connect a portable 12v/200w folding panel into this array if I wish. Now looking at replacing the PWM controller with a brand name "true" MPPT charge controller which will als...

Need help I am going around in circles trying to decide what portable solar system is better or realistic. My choice is between a Powertech 160W with a PWM controller at $280 (Jaycar) or a Kings 160W with a MPPT controller at $180 (Ebay). It is the difference in price that confuses me and knowing that Kin...
