I have 2 x 100AGM in my battery bank. Should I connect source and load to the same diagonals or to opposite diagonals? For the sake of this question source is solar input or mains battery charger and load is house load and/or inverter. I've read a few threads on RV, boating and solar forums and some say on...

After receiving great information about what type diodes to fit to more than one solar panel. I Thankyou. HOWEVER , after reading extra articles and trying to understand about fitting extra solar panels (ie: adding extra power generation) in this esteemed magazine. I can not find any comments ab...

My van currently has a 140 w panel fitted since the van was new, I am adding a 200 w panel in parallel and changing controller to Victron MPPT 30 amp. The supplier of new 200w panel says it has blocking diodes so just wire it in, I don't have any info on the 140 w panel as I would have to break the silicon/ sealan...

Hi Everyone, I have noticed on certain days when there is clear blue sky and the temp is around ~33 or so that our solar panels do not input charge even though we may be down to perhaps 70% SOC. Has anyone else had this problem? The system is 2 x 150w panels and Enerdrive electrics. Cheers RichardK

I haven't got the F/F yet, but it will be about 40 lts. I have heard that a solar panel on it's own can run a fridge during the day depending on amps per hour required to run fridge, so is it possible just to use a solar panel on it's own to power a fridge during the day?. I have a Finch 3 way 41 lt to use instead...

How do I work out which pin is anode as there is no marking and does cathode become the connection to the solar panel and other lead goes solar controller? These diodes I bought from jaycar are flat 2pinsand with metal back plate I presume to dissapate any heat.

Further to my earlier questions. I bought a POWERTECH digital 200amp DC power Meter with 60v max , and have connected up a amp/voltmeter in line to regulator from Solar panels (source) it is reading 13.4 v but no amps reading. Meter is connected so source end is connected to leads coming from panels AND...

Tell me why you can't take 20 year old panels off a house and use them on a RV. It's a hypothetical question. What are the technical issues?

G'day everyone, I ordered one of these Sunmaxx solar blankets (see below) to boost the power going into a couple of 110AH batteries. Currently only have the one 170Watt roof mounted panel.

Hi Helping a fellow member here, I had suggested some 24V 200W panels from a good supplier previous used. However I was looking at some alternative size panels to fit around some items, AC, vents etc on a van roof, and thought I might get some wider, shorter ones for an easier fit. I broused Ebay and loo...
