Good morning everyone. I have a solar system installed because the power in zim is pretty unreliable. The specs are as follows... 1 X Sumry 10.2kva inverter 4x averge 48v 100ah lithium batteries 4 X 310w panels (1240w) 8 X 335w panels (2680w) 10x 410w panels (4100w) Total panel capacity 8020w I have it set to use solar as first priority and only use batteries when the solar can no longer handle the load. We will put the main power on if we need a top up at any time and if it's available. Questions are: 1. What is the best charging current I should be using for mains charging and for solar charging and total for the batteries? 2. What should I set as the float for the batteries and what should be the bulk charging voltage? 3. Do I need to equalise the batteries and if so, what should be the equilisation voltage? Thank you.

I am based in Zim too and have been looking through this thread. My Leoch/Averge lithium ion phosphate batteries are all new and have their original manufacturer stickers on them. They too are 15s and are the 48v 100ah variety. I currently have 4 of them hooked up to my 5kw inverter and 12 x 330 watt panels feeding this all. The stickers on the battery have the following information. If you would like, I will upload a picture of the actual sticker and I can upload the manual that came with them too. Charging voltage 52.5 - 54v Float charge voltage 51 - 51.75v Maximum discharge current 100amps Maximum charge current (stand alone) 100amps Maximun charge current (parallel) 50amps Recommended charge current 20amps

Good morning all, I have a similar setup with an axpert 5kw inverter attached to 2x Leoch 48v 100ah batteries. These are supported by 8x 330w Canadian panels. We get serious loadshedding where I am, (Zimbabwe) usually from 5am until after 10pm each day, so the system has to power the usual household goodies and a borehole and pressure pump for most of the day and then just the house in the evening. I switch off the borehole pump and pressure pump at 4pm after the yard has been watered because I have 5000 litre tank to supply the house. The load during the day is about 1.7kw with everything running and during the evening it's around 500-700w. So as you can see, panels power the system for the majority of the day and then the batteries take over at around 6pm onwards until power decides to come back on after 10pm. I am using the settings you guys have suggested on here for now, but what I'd like to know is if there are any tweaks or adjustments you'd suggest for my sort of situation. I'd like to take care of my batteries so they give me as much life as possible, but at the same time, I want to use as little Utility power as possible too because it's hugely expensive now and also very unreliable. I will be adding another 5kw inverter with 2x Leochs and 6 more panels in January, but for now I'm running the system I described in the first paragraph. Thanks very much and look forward to hearing from you.
