    Solar Panels Do solar charge controllers regulate voltage to batteries?

    This is probably the most stupid question ever..... I have ''inherited'' some PV panels from the previous owner of a property... There are 7 PV panels wired in parallel, actually 8 but one is broken... Wired through a rather basic charge controller, to charge a 12 volt car battery. The systems...

    Trouble with charging a large 12v battery

    Hello! I recently upgraded the 110ah battery in my camper van for a 260ah AGM one. My solar panels (200w via MPPT, soon to be doubled) struggle to keep up with my consumption, so once a week I hook up the battery to mains using CTEK's 5A charger, which supports AGM batteries but is not...

    Current limited charge relay

    Hi there, I am looking to charge an auxiliary windlass battery (130Ah lithium) that is located 35 feet away from my main bank (1030Ah lithium). My charging input will range from to 40 to 100 Amps, but I need to keep the wire size to a maximum of 6AWG. Do you know of any current limited charging...

    As above, I've been asked by a solicitors for a copy of a MEIWC I did back in 2016.

Their fees aint cheap. If it had...

    How fast should a capacitor lose it's charge?

    I've been testing some capacitors off a treadmills PCB using a 9 volt battery to charge them up, then taking voltage readings with a multimeter and watching as they discharge. Most seemed to release the 9v very slowly but one 25v 470uF capacitor leaked it away considerably faster than the rest...

    How to earth SWA to external EV charge point

    I am looking at section 722 of 18th edition for EV charge points. Section 722.411.4 imposes restrictions on the earthing arrangements for TN systems. For an external chargepoint connected to a domestic PME supply the accepted solution to avoiding the restrictions of 722.411.4.1 seems to be to...

    Earthing solutions for EV charge points on lampposts.

    Hi guys, Does anybody have experience of installing EV charge points on lampposts- I am unsure how often the lampposts' earth can be used especially if TN-C-S and how the 18th edition might indeed rule this out. If the earth cannot be used is it a realistic solution to install just one copper...
