May 6, 20242 yr Hello folks, Unfortunately, my almost two-year-old inverter broke and it was sent in for warranty. Now I have connected my old inverters and unfortunately the US5000 went on alarm this morning with these settings: 05: USE 12: 48V 13:51V 26: 53.2V 27: 53.1V 29: 46V and when I switch to setting 29 to 47.5 the diesel generator continues to operate at high load. These batteries are connected 1x US5000 and 4x US2000C I would be very happy about your tips and kind regards from Spain. Edited May 6, 20242 yr by rafa2

May 7, 20242 yr Author So the settings are current, the dishwasher and the oven ran today without the generator starting: 02: 50V, 05:USE, 11: 50V, 12: 48V, 13: 51V 16: SNU, 26: 52.5V 27: 51.8V 29: 46,5V Unfortunately, last night the generator started with these settings: 02: 80V, 05:USE, 11: 30V, 12: 48V, 13: 51V 16: SNU, 26: 53,21V 27: 53.1V 29: 47,5V Edited May 7, 20242 yr by rafa2

May 8, 20242 yr If I set the dip switches on the batteries like you have them now, I get no comms among batteries and the inverter when working on PYL mode. Have you tried to set parameter 5 to PYL and let the system work with proper comms?

This is an old inverter (approx. 2014 model), it only has the USE in 5. I hope that the shop will repair my new one quickly. 7 minutes ago, Mauritius B said: If I set the dip switches on the batteries like you have them now, I get no comms among batteries and the inverter when working on PYL mode. How are your dip switches set up? Because I think the dip switches are compatible with my new Axpert 5KW 48v Mppt 80A/500V VM III...

Only master battery has DIP 1 on and the rest, all DIP's off Edited May 8, 20242 yr by Mauritius B

The value used is the lower of these two values: setting 12, and setting 29 plus 2.0 V. This is lead acid thinking. To avoid this, you could use LFP flavoured fully patched firmware. If you tell me your exact model, or existing main (U1) firmware, I can post a link to suitable patched firmware. The LFP flavour of fully patched firmware reduces this "gap" to 0.5 V. More detail in FAQ #2. Even with setting 29 at 46.5 V, you are switching to grid/generator at a battery volage of 48.5 V. Factory firmware has no battery internal resistance compensation; patched firmware does. This feature that we call KettleKomp™ can dramatically reduce the switching to bypass mode (using the generator to run the loads). It's not perfect, but way better than factory firmware. I assume that settings 02 and 11 are actually in amps (being total and utility/generator maximum charge current respectively). Edited May 9, 20242 yr by Coulomb

Why only the US5000 went into alarm state? what about the US2000's? what was their SOC?
May 9, 20242 yr Author first of all thank you! I'm not sure why the US5000 went on alarm. Unfortunately, one of the US2000Cs is swollen and no longer charges properly. Since the US2000C was on the minus and the US5000 on the plus, I can imagine that this had something to do with the fact that the battery that was swollen only had one diode on in the morning, the remaining four or so.

The LFP flavour of fully patched firmware reduces this "gap" to 0.5 V. Are these photos enough for you? Because I have no communication with the inverter and solarpower because I don't know if I built this cable for my new inverter.

May 10, 20242 yr This is the fully patched firmware that is compatible with your inverter; choose the LFP flavour: https://forums.aeva.asn.au/viewtopic.php?p=70827#p70827 That light grey cable looks like the original cable that would have come with the inverter. It's plugged into what looks like a USB to serial adapter. If it's a suitable one (not all of them work for unknown reasons), you should be fine for firmware updating. SolarPower is for on-grid (grid interactive, Infini) models. WatchPower is the monitoring program for off-grid inverters such as yours.
May 13, 20242 yr Author Thanks, I won't do the firmware update until I have the other inverter here at home, I don't want to sit here without power. edit: The update worked, thanks again! Edited July 8, 20242 yr by rafa2
