All things Sunsynk (Deye, Inge, etc...)

Is there a safe amperage to use here that won't damage the batteries/something - or will the BMS limit what the batteries can charge at?

(Hubble AM2s - we have a four hour slot shortly, and no sun - and batteries currently at 50%)

@AfricanTech , in loadshedding now, what do you want to see from the portal?

so yeah, pretty sure what I said was correct, the 230V setting is for when there is no grid detected.

Its just granular control so that you can control how much power it should draw from grid if it needs to charge the batteries.
The safe amperage would be what your battery recommends, your BMS should control the max but the inverter can limit it below the BMS max based on what you set there.
You might want to slow charge it just to hold out for sunlight or something along those lines.

EDIT: Just to add on for your AM2's I see they support 1C so 100a. If you are worried about loadshedding with no sun then you can set the grid charge value to 100a which equates to about 5000w charging. But probably better to set it to about half that, but all depends on how fast you need to charge.

Tx, yeh - it won't happen often - just days like today when the batteries haven't charged and we go into a four hour loadshedding slot.

What happens when you tap LN 220VAC then use the up and down buttons below the screen?

I see these screens

Thanks. That's what I was looking for - so my system seems to be under-volting when running on battery.

This is the one I was talking about where you can set the voltage. Inverter output Voltage.

This will only apply in the case of no grid, otherwise grid sensing will be used to synch.

Thanks - my installer will be here tomorrow so I'll check with him to see if it's okay to adjust that value.
 
This is my tweaked work modes setup now with stage 6 in the mix (10kWh storage).

Decided to bump the 9am-1pm slot to 75% minimum as my geyser kicks in at 12 and wouldn't want it draining the batteries if they're not charged enough (which would also indicate bad solar output).

Have grid charge to 50% enabled during the evening so it can top up when there is load shedding. So far this seems to be working okay. I'll have to wait and see in the dead of winter though, but hopefully should have my third battery by then.

Mine looks like this:

10kWh storage as well, with battery shutdown at 20%.

I'm too worried to drop mine below 50%, when load shedding hits in the evening my battery can get to around 35-40% with a 2 hour slot, would drop very close to that 20% mark with a 4 hour slot. I might even bump it up to 55% now.

I had mine set at 50% when we still used the air-con that is on essentials. Now that is cooler, we do not use that during the night. The biggest power user during evening load-shedding would be the kettle, followed by the TV. As soon as we go to bed, the base load drops to almost nothing.
 
I am suddenly having issues with Solar Assistant's MQTT data not showing in Home Assistant. I have the bridge setup and running Mosquitto inside HA, this has been working for months. Today the SA data just disappears and I have to restart the Mosquitto broker to get it to show again. This is possibly after a HA restart because I was updating integrations last night and this morning. So possibly after restarting HA the Mosquitto broker is not connecting to the SA broker correctly and has to be restarted again?

Ye, my base load is around 400-600W.
