I see this in the spec sheet: "Supports peak shaving control in both "self-use" and "generator" mode"

The generator is nominal 1,800W so I'll set the maximum charge to 1,500W which for the 50V battery is 30A. I'm getting a professional electrician that have experience with this type of installation, so a CoC will require a breaker I am sure. Thanks for the feedback everyone.

I've been told the Solis inverter actually has a dedicated generator port. So that is obviously the best approach. I'll just limit it to say 30A (1,500W) and it will take 3-4 hours to charge.

Thanks to @HennieL , @Pho3niX90 and others in the following thread I got the charge rate of my inverter battery sorted. I have a follow up question due to the recent storms. https://powerforum.co.za/topic/33856-slow-charging-sunsynk-5kwh-battery-at-only-180w/page/2/#comment-227998 With the recent storms the grid was out for many days and there was basically no sun (I don’t have panels yet but in any case there was no sun so it would not have helped). My battery only lasted a day so we were without power for a few days. I decided to a get 2,000W inverter generator to top up the battery and supply some power to the house during such conditions. I have a Solis 5kW hybrid inverter and 5kWh Sunsynk lithium battery. An electrician will install a change over switch so when the grid is down I can connect the generator safely to the AC supply. I have a few questions: If the battery is partially charged and we’re on generator, when I boil a kettle will the inverter blend battery and generator power to supply the load? Kettle can draw more than the inverter generator. What settings should I change in the Solis app. The most obvious is the max battery charge rate. Currently it is set to the nominal 50A (max is 100A). If the battery is 50V and I want to charge at 500W then I need to set it to 10A, correct? That leaves 1,500W spare for the house, correct? Will the inverter automatically know what the generator can output? The inverter generator: https://www.takealot.com/steco-sg-2050i-steco-inverter-generator-2000w/PLID94464184

Yay, it’s working! Thank you @Pho3niX90 and everyone that commented. Much appreciated. A bit sad that Solis SA support said it’s a battery issue and they can’t help. Will get solar panels this year and will then set it to use down to 40% SOC overnight. Don’t want to go lower in case of outages or lack of sun.

Thanks very much. Will feedback with the next power failure (don't hold your breath).

Currently no solar panels so yes it's for backup.

Like so?

I don't have solar panels but I found this option: Inverter/Inverter Control/Storage Mode/Charge&Discharge Slot and I enabled Slot 1. Let's see if this makes a difference. If this it then it's a pretty well hidden option!

I selected Lithium LV as instructed by Solis.

Check my photo from three hours ago, 64% SOC and charging at 180W.

Turned off the battery which stopped power to the house. Had to switch from inverter supply to Eskom supply to get power back. Waited a bit and turned the battery on. After a while the inverter saw it and I could go back from Eskom supply to inverter supply. It's decided to do a top up, still only 180W:

I have been in contact with them, they updated the firmware but it didn't make a difference. I have asked now if they can remotely check it. This is what it charged at recently:

Battery Settings Maximum Discharge is set to 100A, but the battery reports 0A. See above. I don't currently have solar panels, so I charge from the grid.
