Thanks for that info, much appreciated. Off Grid, stand alone solar. No 2 Bank was built specifically to give me power when No 1 Bank gets low on charge rather than use the diesel generator. With the cost of diesel fuel here in South Australia it made good economic sense. I can monitor No 1 (and have) from anywhere in Australia, to monitor No2 I have to walk to the battery shed. Guess who's buying another Pi today? I'm not a shill for SA but it works for me, 24/7 and I'd be lost without it.

Hi, I've been running SA for almost 12 months on a Pi B4, very happy with it. I now have a 2nd system up and running as a backup, Panels, MPP Solar 5 kW inverter, 4 x LFP batteries and a Victron BMV smart shunt. What I'd like to know is whether I can connect the no2 system to the Pi or do I need to purchase a new Pi and run a 2nd instance with a separate URL? Thanks, Keith

Sorry, that was meant to be DC

My current battery bank consists of 12 x 260 Ah SLA batteries wired series/parallel to 48v, so essentially 3 x 48v batteries. Had a bloke in Melbourne make up the cables for me, the lugs are machine crimped and insulated, a veritable work of art. All the connects and interconnects are the same length, so are the positive and negative leads to the controller, the way the controller is situated the positive lead could have been about 400mm shorter but it made sense to me for them to be equal in length. Some things I just take as read like not disconnecting AC whilst under load, I'm assuming doing that could let the magic smoke out, not something I want to get familiar with. So far this bank has served me well for 3 years now, when it fails I plan to replace it with a Li Ion battery (with equal length connectors)

G'Day all, Just need a bit of advice please. Off grid, stand alone Solar, 12 x 260 Ah batteries wired to 48v. I've got an 8600 watt generator which I start up once a month just as part of routine maintenance. Never hooked it up to the inverter as the PV input has been more than sufficient for our daily needs and to maintain the SOC of the battery at about 80% This system has been running since November 2019 to the point where it's almost boring, PV in AC out, it just works We're in winter here in South Australia and the last few weeks the weather has not been conducive for good solar input so the battery has copped a pounding, I'm using a 48v charger to supplement the PV input to maintain SOC. I should be able to do this via the inverter, which has 2 wire start capability as well, problem is I can't get the inverter to go into bypass or line mode, it sees the AC input but doesn't want to play with it. MPP Solar in Sydney have been great with their support but at this stage I'm thinking the problem exists between me and the equipment, so can anyone point out the error of my ways please.
