Hi All, Just to wrap this one up I can report that the problem was in the control board in this instance, and having replaced this board it is now working again. Thanks for all who helped with advice, especially Jay and Kris. cheers Hugh Hugh Piggott Scoraig Wind Electric Dundonnell Ross

Re: [RE-wrenches] heating lithium in cold weather

I am trying out an insulated box and small heater. It doesn't get very cold in West Coast scotland so 120W seems useful. Also automatic vents used on greenhouses, to open up the sealed box. On Fri 17 May 2019, 18:09 Dave Angelini Offgrid Solar, wrote: > The risk may be worth it if the battery

Re: [RE-wrenches] Low Voc for effective string?

Hi All, This is a very interesting thread for me. I like low cost renewable energy, and I don’t jump to buy MPPT charge controllers when I believe that the setup I am planning works close to Vmpp inherently. I find that the panels used for grid tie with Vmpp around 31V actually work

Re: [RE-wrenches] Conext SW 4024 with bad firmware

hi Lou, I don’t wish to contradict this version of events but if true then it will make the inverter unsuitable for most generators. Here is another scenario I have seen a few times that looks similar but can be fixed. The inverter charges the battery etc. and decides to turn off the

Re: [RE-wrenches] Grid neutral

for a neutral, but where a number of diverse circuits are connected there will be some imbalance, so you need a wire there, but it need not be as heavy as the 3 “hot" ones. cheers Hugh Hugh Piggott Scoraig Wind Electric Dundonnell Ross shire IV23 2RE, UK +44 77 1315 7600 h...@scoraigwind.

Re: [RE-wrenches] New washers and dishwashers on inverter power - any problems?

We have a pair of VFX inverters and we run an LG dishwasher which is great - quiet direct drive - uses about 0.7kWh for a wash (and about 0.2 per 24 hours sitting there looking inert :-() It worked fine before the second inverter was added actually. As did the induction hob and the halogen

[RE-wrenches] common ground on fm80 aux output?

hi wrenches, I am installing some load controls for a client who has a FM80 controller. I don't have experience with this product. It has a 12V aux output that I wish to drive an SSR but the wiring is complicated by the fact that this SSR also needs a power supply as well as a control signal.
