Another two weeks gone and I tell you - this is frustrating. No contact, no update. Today someone asked me who they should speak to about going off-grid, they are building a home and they want to do everything up-front. All I could say was "stay away from ZASolar and Revov". What does a 10-year guarantee help you if the supplier is useless? I'm at wits end, after an entire 8 months I am in the dark by 8pm every night. Wow. I hope people search the forums before they take the plunge.

Sadly I found out that I'm using the "wrong" ICC software. It seems there are two versions, I have the one supplied by Centurion Solar. They do not cater for Revov, as far as Revov is aware. Some news though - Revov was at my house and drew logs from the BMS. They also swapped the BMS cables to ensure it wasn't that. It seems we all agree now that it is a battery problem. They wanted to take my battery in but since I am off the grid, we are first waiting for a loan battery to become available. Sarel has been a great help and hopefully we will have this sorted out by the end of next week.

Thanks!

So I measured the battery using my Fluke. It seems to stay at 54.0V max. ICC and Axpert showed 54.2V but battery at 54. I also increased the cut-off voltage to 48V, that is the highest ICC let me. Upping the voltage made no difference though - at 9PM last night we were in the dark again ;(

Thanks for the reply. Fully charged - the light on my Axpert stops blinking and stays green My cut-off is set at 47.5, and I basically hit that every night now. At 49.5 the Axpert starts beeping (I leave that on to warn me) - and I go into "Eskom Load Shedding" mode - I switch it off. I have various UPS's to run all the necessities - and a squad of power banks! I'll measure the battery tomorrow when it's "charged", the Axpert/ICC reports the voltage but I'll use Fluke to see.

Hi All, I've wanted to post many times but I don't think I have - so firstly thanks for a great forum, I love reading about how passionate you guys are! Just as an intro - I'm an IT guy with electronics as a hobby. I don't mind tinkering as a rule I'm off the grid, I have about 5k of panels, Axpert 5kVa inverter (stock standard, not flashed). Started with LA 4 years ago but then about 9 months ago installed a Revov 10.2kWh pack with ICC. My home is automated using DIY stuff - Domoticz & sonoffs (on Tasmota) basically. Siri is integrated so even my wife loves it! I don't mind sharing any experience, ask any time. Now my issue - my Revov pack doesn't seem to deliver on it's potential. Especially now in winter, I run out of power early in the evening. I don't think it's because it's due to the reduced hours, I think it's because the pack is not loaded fully when there is sun. So I did a test - I waited until the batteries were "fully charged", ICC showed PV was "cut off", at that stage at 54.2V. Then I disconnected the panels and waited for the power to cut off. ICC shows this was 2.2kWh later. A bit disappointing I think. I called my installer and he suggested I add a Victron device (not sure what it was) as ICC and the Revov BMS seem to not be on the same page. I just don't have any money to spend, so I stopped listening at "Victron", sorry. I obviously want to use my current equipment, the Axpert has been fantastic and I've had no issues at all. So he suggested I raise the float/bulk to 56.1/56.2 V, to see how it performs. Initially they were 54.5/55.5. I don't like the "let's see what happens", hence my seeking advice. Has anybody done a similar install? Or even without that - any suggestions? Not sure what data I should be posting here - I'm sure there's "things" on ICC that I should be providing, please tell me and I'll deliver. Thanks in advance!
