This is absolutely correct. I actually found a third generator that had no MEN and this didn't trip in the same way. This genset was tiny so it really struggled and would keep tripping it's RCD, but at least we could get some power into the battery eventually - enough to wake the system up...

My neighbour lives off grid like we do. She has had no end of trouble with her "state of the art" Selectronic SP Pro off grid setup, but yesterday her 7KVA diesel generator refused to start so I took up my 8KVA petrol generator to swap it out. Pretty simple really, unplug the broken generator...

OK so I had a catastrophic failure of my Growatt 12KW inverter and needed to get something up and running quick and cheap for my 48v lithium battery bank. I bought 2 Epever 5420AN charge controllers and will pair them with a cheap chinesium 48v inverter while the Growatt warranty process inches...

I've had no luck with the software because there is no wifi access anywhere near the inverter so the dongle won't work. I've yet to connect a data cable to the inverter but perhaps if I get some time in the next weeks and a long enough cable I'll have a play around with it. Honestly, some...

OK so I've had some luck but then ran into another couple of problems. The unit settings that seem to work for me are: 01 - UTI 02 - 80A 03 - APL 05 - USE 06 - LTE 08 - 230 09 - 50 11 - 40 12 - 50V 13 - 56V 14 - SNU 19 - 57.6V 20 - 57.6V 21 - 48V 23 - DIS 24 - 57.6 The generator would...

Actually there seems to be 2 lithium battery options LI and US2. I was using the US2 option because the inverter will only talk to the BMS of a Growatt battery. When I was on the phone to the Growatt rep here in Aus he suggested using USE instead and we set up the appropriate settings in 19...

01 - UTI 05 - USE (advised by Growatt tech, although I previously was running it on US2) 11 - 10 Amps. (The generator has duel 15A outputs but annoyingly the inverter can only select 10A or 20A, not 15A) 14 - SNU

Yeah the switch on the front is a 3-way switch with a confusing array of options. ON (Power Saver), OFF (Inverter) and ON (Inverter). After talking to the Growatt support guy he said never use Power Saver because it doesn't do what you'd think it does, so I never have. The OFF switch isn't...

I don't think this is settable. The inverter chooses the mode based on conditions I think. Regardless, when it's in 'Line Mode' it still seems to refuse to charge the battery from the generator unless the battery voltage is low.

To be fair it's early days for me on this inverter. I had a much smaller, much simpler MPP solar 3024 system running on lead acid that was fairly straight forward. The issues I'm having with the Growatt are related in part to my lack of panels - I'm pretty sure if you had 6kw of panels it...

Hi all. New to this forum, looking for help. Some background: I live 100% off grid in Australia. I used to run a lead acid/ mpp solar system which did well, until it recently died in a very weird way (but that's another story) and found myself in the situation where I needed to install a...
