Hi everyone, I thought I would start a new thread about batteries or more to the point brands, to date the only Lithium batteries I've had anything to do with are 18650's and my 17.5Ah kayak battery which I use a dedicated Lithium charger to charge both types, I've been searching the net for information...

G'day people, I'm looking at upgrading the ET 55w panel on my pop-top & going to a larger panel. That is if I can get three of the four mounting feet off the roof without doing any damage. Output power is not a major consideration as our power needs are low, however weight is - I'm not getting any younge...

Our van has been in storage for the last two years. The invertor was accidentally left on and now the batteries have zero charge. I had the power connected all day, but no sign of any charging. Are they dead? Gel batteries about seven years old, hardly used. Collo.

I have 2 x 190watt house pannels on van which produce 36v on a sunny day and going through a Victron Mppt controller 100/20. 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 folks, Ive just mounted a Redarc 180w panel on the roof of my new Toyota HiAce. I installed it last night and drove today with what sounded like a bad French horn player sitting on the roof whenever I got up to about 80kmh ! The din was/is quite horrendous ! The panel itself is 35mm thick and Ive placed it...

I have 2 of these (House) panels in parallel with a Victron 100/20 am I correct in saying although they 36 V they will only produce aprox 10.3amps in perfect conditions and if that is the case then are these not ideal on the Caravan ?? ?

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.

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...
