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

I got it all going but having trouble with my cable. I already had an FTDI based TTL-232 cable which had a header on the opposite end to the USB. I soldered a DB9 to that using pins 2,3,5,7,8 but am getting CRC errors.

I emailed their support but my experience is that's a black hole... Anyone know whether it operates in 3 wire mode (Tx, Rx, GND) or do I connect all (except VCC I assume)?

I might just go grab a cable off the shelf. Not going to buy one from them until I hear back from them. I don't trust them to actually send me anything.

I got my RS485 cable directly from them. Stupidly overpriced, but I didn't feel like hacking.

Their shipping was very fast.

I think their prices are in line with anyone else, the licensing of the chip is what costs the most. Maybe I'll go with their cable...
Strange that they ignore support emails though.

I don't think its malicious - im not sure they have a proper support team so the dev replies when he can

- they probably do need to employ some L1 support people to ease the load

Wouldn't stress, they have these maintenance periods now and then but eventually come back.

I've found that the logger usually logs the overall production/consumption stats, it's only the graph that goes wonky...

Yeah my graph is shot but the totals are there.

What's weird though is that one 1⃣ guys suggestion, I downloaded the Deye cloud app, it uses same credentials as Solarman. But there is a 1kwh differance in purchased power between the two. Output and battery all match.

*edit* nvm it's matching now

I ignore the Sunsynk dongle.
I’ve got it installed but to log onto another network every time to read it is not for me.
I‘m retired so its a short walk to read the info from the touchscreen.
Solarassistant with the pi is probably the better way to go - but at a price.

Mines not so close but I would have expected better IOT.
 
For those with Deye's/Sunsynks that came with the wifi dongle, what would be the best recommendation. Stay with Solarman or go solarassistant? I believe both are compatible with HA

You could always just try a Solarman HA plugin first before buying Solar Assistant because it works with the existing dongle...

That depends on your usage scenario. If you need second by second data, or want to make regular changes to inverter settings via HA then you will need solar assistant. I use the stock standard solarman integrated wirelessly to HA which is more than sufficient for my needs.
 
Side question. Many folks believe in cost cutting with a geyser timer off switch. Based on my monitoring of my homes power, it really doesn't look like it will do much. On standby, my geyser is drawing under 30W. Plumbers recently told me a while back that modern geysers have internal insulation even better than the old school geyser blanket and a well maintained Geyser will only draw enough power to maintain its internal heat.

From my usage

The first cluster of evening spike is our electric stove, the second big one is the geyser when the family bathes ( we normally do our kids first and then wife and I after ) and we use the geyser in one slot really. So a timer doesn't make sense to me because the "resting" draw is so low, have a look at the beginning, our nightly draw is around 350-400W for the home ( including geyser and appliances ).

Anyway, not so much a question but a statement, is the whole Geyser timer thing worth it? I was seriously considering buying a smart wifi isolator for the geyser for regulating it but based on that graph and patterns, waste of time.

No. Been discussed to death on the forum. Geyser timers don't save electricity (although they do help with managing load for solar)

The benefit of the timer is to control the load. You can schedule the geyser to come on during the day to run off PV so it doesn't draw any battery.

Since you have a 5 kW inverter, you'll also know exactly which hours the geyser is running so you know not to run anything else and trip your inverter...
 
This logging software is on the fritz again but there was quite a large maintenance window so lets see.

Because my geyser is fully electric, its specifically not on the load circuit as well as the stove, no danger of tripping. But I hear you in the case of a full off grid, makes sense but I would then probably switch it out for either a gas or maybe direct, 5KVA would not be enough to cover my home total, 8KVA maybe.

As per the other replies, no you won't save with a timer. A geyser at say 60C should lose only a couple of degrees C per day due to standing losses. The only way to save is to reduce your usage (shorter showers, colder water etc).

A geyser is also only on or off (normal element geyser), so there is no 30W standby. That is something else in the house turning on and off. On it will use 3kW (or whatever element you have) and off it will be 0.
