December 22, 20214 yr I have a problem that i cannot get my inverter to produce output power as a first priority from the batteries/PV while grid power is available and connected. Even though i have selected SBU or SUB any suggestions what the cause can be?

Even though i have selected SBU or SUB any suggestions what the cause can be? If I'm right that Kodak inverters are built by Voltronic, your problem might be the setting 31 (solar power balance). It should be set to enabled (SbE). Edited January 13, 20224 yr by Beat
January 17, 20224 yr Probably worth checking what your back-to-discharge battery voltage settings are on SBU, if it's too high, your batteries will never hit that voltage and you'll always be on grid power.
January 17, 20224 yr The Kodak is a kind of Voltronic as already mentioned. I would check parameter nr. 01- Output Source Priority (SBU) 12/13 - Preset voltages for back-to-utility / back-to-battery 16- Charger Source Priority (SBL UCB) (CSO in Kodak menu) 29- Low DC cut-off preset voltage As I can read in the Kodak manual, there is also a timer for the output source priority and the charger source priority. Check that no time limitation is set on the timers. I hope that helps. P.S. If not done yet, maybe you can use Watchpower software to configure the inverter more easily.
January 17, 20224 yr Author Thanks for the feedback I have found that the back to battery voltage on the output source priority was set at 53 volts and the pylontech battery was only getting up to 50 volts i set the voltage down to 50 volts and everything is working as I think it should. Thanks
