Sigenergy Setup questions

Sigenergy Setup questions

Hi all

(Crude wiring diagram for context)

Looking at getting a Sigenergy solar/battery setup on my property

We have the main meterbox on a pole in the middle of our property, and 4 buildings connected to individual 63A circuits that then go to each buildings respective subpanel.

We also have a diesel generator connected to a changeover isolator switch in the main meterbox on the pole which lets us flick between mains or generator for when we have a power outage.

We are looking at 18.5-24kW of solar on the main house, with a 48kW battery (potentially over 2x inverters w/ 3 banks per inverter). Hoping to have the battery service the entire property and not just the main house.

I know the inverters and gateway are limited to 12kW capacity - but we can consume up to 20kW of power at any given time. Unfortunately we are only single phase and our grid does not support a 3 phase upgrade.

I understand the parallel inverters which allows this to go up to 24kW throughput to make full use of the solar panels to charge the battery more efficiently, but I'm confused with the gateway.

Installer is saying we can have the batteries/inverter on the main house, and the gateway at the pole (and somehow 'trick' the gateway to use the main house's circut to feed the battery into the gateway)

the gateway is still only 12kW limited though, so what happens if we are consuming 20kW?

Assuming 12kW through the gateway from the battery, and 8 from the grid? But what about during a power outage, or when the generator is active?

I would assume that we could wire up the gateway from the output of the generator changeover isolator switch so it would think the generator is just a standard 'mains' input so it can make use of the higher throughput vs hooking it up to the backup input?

I thought I saw somewhere there was an upgraded SP gateway (HomePro SP-F) that could support 100A mains and multiple inverter inputs, but I can't find much info about it on whether it is still limited to 12kW total or not.

Any advice or feedback welcome

Thanks in advance!

Mahlkonig E80S motor jerking while idle

Apologies if this is the wrong subreddit to ask this question. We have a Mahlkonig E80S grinder that has suddenly started jerking repeatedly when powered on.

When pressing in the dosing button, the motor spins perfectly normal - it only does this when idle.

There is a push-button under the front display panel that when it is 'on', the motor also spins up to full RPM without any jerkiness.

Anyone had anything similar or could point me in the right direction?

We have already replaced both of the main capacitors but this has not resolved.

TIA
