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

Maximum power current.
But voltage generally more important cos if you exceed the volts, you blow the inverter.
For current, your inverter will clip the panels to the inverter max. So a 11a inverter will run a 13a panel at 11a.
So it just results in your panel never reaching the max power its rated at.
Technically they both important, but 1 will damage the inverter.

Agreed both are important, but both will also damage the inverter. The max Isc is printed on the sticker on the side, for the 5K it is 16.5 amps, if you exceed this you will blow the MPPT controller.

Not sure what you mean by this question? Which screen should I look at to obtain that information?

Page 28 & 36 in the manual: system setup, grid setup


Depending on the firmware you should have something for SA grid in there. If not have the firmware updated. I don't own a Deye, mine is Sunsynk.

All that said, 220v won't be a problem if the Hz are correct AFAIK.

This setting?

Hi guys,

Anyone had the below happen.

My timer is on and the following is my current setting (only showing the sections relevant to the issue):

Time SOC Grid Charge
00:00 - 08:00 85% NO
08:00 - 17:00 100% NO
17:00 - 00:00 100% YES

How this usually functioned is that between midnight at 8am, it would use the battery down to 85% and then use the Grid to cover load.

Last night, we had load shedding until 22:30 - I saw that we had no load shedding until later next day, so decided to change above settings to rather that between 17:00 and 00:00, it would not grid charge.

At the time of power being restored at 22:30 last night, the SOC was 72%.

However, even though battery setting was 100% on timer page and SOC was at 72% at that point, it kept drawing small amounts of power (like 20w) from the battery for the rest of the night and morning?

Would appreciate it if someone with a Deye inverter could check what the Voltage shows when running on battery (used the Deye weblink (https://www.deye-icloudhome.com/plant/infos/device)

Mine shows the following during loadshedding

When not loadshedding it shows:

I'm wondering whether

1. this is why my Shelly Dimmer 2 Switch misbehaves during loadshedding and,
2. there is a setting that I can change to force the inverter to output slightly higher voltage when running on battery?

My grid and output voltages are quite high, 240 odd.

Normal for now but I do get battery discharge later.

When I get shed again I'll do a check unless you know a way to check historical?

Keep in mind, my inverter voltage should be higher than grid so that its consumed first as I understand. Also, according to the installer at the time, the inverters senses and adjusts that accordingly with the flucatuations in grid. There is a setting somewhere on the grid screen where it does state output at 230v, I assume that may be the fallback voltage with no grid connect.

If you are connected to grid the voltage and frequency you see are what is coming from the grid. The inverter has no choice but to match this.

With no grid available the inverter should maintain these at constant values. It will aim for 50Hz, and my Sunsynk sits at 231V. Much more stable than grid power. But even going down to 220V shouldn't be an issue for the dimmer. My 1 Shelly dimmer also gives issues, but not loadshedding related. Sometime just goes offline and I have to power cycle it to get it back. The other one is much more stable so maybe just a bad device or config on that device?

Thanks. That particular device is definitely sensitive to voltage - when running on mains it very occasionally has to be power cycled (the load from the light bulbs is actually under spec at 18w [3x6w candle style led bulbs] - it really requires a 20w load but for the life of me I can find 7w led's) - when running on the battery it 'kicks out' almost immediately and I have to switch it off completely.

Strange. I have a Shelly Dimmer 2 running 2x 8W LED's and that is the stable one. The other one is running 18x LED's (5W I think) and this one loses connection sometimes. I think the 20W is if you are using it without neutral, with neutral it only needs 10W. There is also the bypass you can fit to try and improve it?

Wired it up so long ago I can't remember anymore.

Should open up to have a look.

The full list of timers need to account for the 24h cycle from top to bottom.
I suspect you have an overlapping timer setup, hence the no charge from grid last night.

Hey man, made sure no overlap - been working fine for a month now.

Just last night that it did this
