September 29, 20214 yr Hi guys. I hope someone can help me out regarding settings on my system. i have : 1 x Growatt SPF5000-ES inverter 1 x Revov 5.1KWh Li-Ion battery 12 x 330w panels laid flat on a flat roof Depending on the day and weather. I can average around 10-12Kwh a day. I’ve been reading on the forum that people have been monitoring the SOC etc and some settings. My settings on 12 and 13 won’t allow me to change away from 50. Unsure why. My battery selection in setting 5 is USE anyone able to help? I can supply any info you need.
October 2, 20214 yr Hi Howard D, Could you Please check that the following settings are set correctly. 01: SOL 02: 40Amps 03: UPS 04: DiS 05: USE 06: ENA 07: DIS 08: 230v 09: 50hz 10: 4 11: 30Amps 12: 50v 13: 54v 14: CSO 15: ON 16: ON 17: OFF 18: ENA 19: 55.5v 20: 54.5v 21: 48v We don't worry about the reset, many thanks. Best Regards Thibello

Best Regards Thibello I've experienced if I set 1 : to SOL the inverters switch to Eskom the moment the sun goes down.

Best Regards Thibello Thanks very much Thibello. My setup is currently on SBU and seems to be working pretty well. But on SOL the inverter tends to cut off PV production as the battery I think reaches 100%. id like the battery to discharge to 30% and charge up to about 80% or 90%. Will the above settings get this outcome?
October 2, 20214 yr Author Will be using the above settings and monitor the system and revert back with the results. Thank you again.
October 2, 20214 yr The setting to use battery at night on the ES is bat first on parameter 1. It behaves the same as SOL during the day.

October 3, 20214 yr Info on the last 12 hours. After a bit of a struggle and a few trips, I think I finally got the parameters settings to my satisfaction.

No, we are using Modbus interface via USB, I'm not the one doing it, my son is the one busy developing the software for me, I'm clueless when it comes to software design.

Ok great, was just curious. I will see if I can do an export of my grafana dashboard for you to try, you should be able to just change the data sources to match your outputs

Thanks Antonio. I will show you my graphs from today. so I’m not sure what readings should be etc. but I will say that I’ve left the system on SBU since yesterday. And it hasn’t used much municipal power compared to usual. I could probably do with a second battery to help store PV that is generated. And I’m sure I’ll generate slightly more PV as well once our panels fitted at an angle. Currently just installed flat on our flat roof. Our geyser does make the system spike incredibly, but will be changing the element to a 1.5Kw version. That should make a huge difference in usage. if anyone would like to comment or suggest anything to the above graph. Please feel free. thank you

Please feel free. thank you Howard, After lots of experimenting on my system I've found that SBU was the most suitable in my case, I have 2 X 5000 KVA and just one battery, looking at my graphs I'm not making use of all the power generated by my panels. I have to invest in another battery. So far I've managed to get my geyser ( 3 KW ) to temperature and enough accumulated energy in the battery to do all the cooking in the evening. I've managed to reduce my daily consumption to just +_ 5 KWH using setting SBU from about 16 KWH with setting SOL. Also I have setting 14 on SOL, I don't want to use Eishkom power to charge my battery. By the way I think we were colleagues @ ABB.

It took ages for us to get to a point where we can use the system for what it is meant to do. But yes, I think an extra battery will do wonders. I think at some point we may invest in a second 5Kw inverter and another battery. But so far it’s not really overloading with our current geyser. Which I think is a 3kw as well. Which we will be changing to a 1.5Kw shortly. Also, I will experiment with setting 14. Currently on solar and utility. Sorry bud, I was never an employee of ABB. 😉
