SauRoN's SomeWatt Solar Install

RonSwanson said:
Restart is the battery voltage or percentage where the inverter recovers from a shutdown state. Shutdown happens when a particular battery voltage or percentage is reached. It is not totally shut down, it is basically in a standby state. In the Sunsynk inverters, the screen goes off, and it is able to charge batteries. When the batteries are charged to the restart value, the inverter "restarts" i.e. it resumes normal operation.

Why are you using AGM values vs battery comms?

So they should have called it something sensible like "Startup" rather than Restart.

See here for why the AGM values.


It's not actually using AGM, but there's an oddity with the Sunsynk where those values are still adhered to.

Yeah, I remember that famous video. It could be that the "standby mode" uses voltage vs comms.

So you confirm that you are using CAN comms for normal operation?

Oh yeah normal operations it's always on Lithium CAN.

Normally reserved to 20% but then under grid loss meant to go down to 10% but this problem started coming up where it would just shutdown at 14% instead and then I remembered seeing this video at some point.

So now I'm hunting for the ideal voltage numbers to equal 10% shutdown. Now that I'm pretty sure this is the problem I'll just step it down 1 volt at a time until I win.

Let us know when you do please, would likely apply to myself and others with a Dyness as well...

Quick Q, how did you integrate the Sunsynk into Home Assistant?

I have the WiFi dongle thing with my Sunsynk 8kW.

If you have Solar Assistant then you don't need the github code. Solar Assistant allows direct into Home Assistant via mqtt.

If you don't have Solar Assistant then there are other integrations that can pull info from the inverter, some of which require github code.

Solar Assistant requires more hardware in the form of a Pi which is what I was trying to avoid.

You don’t need to touch the code, it’s just a link to the source, the integration is simply point and click in Home Assistant.

What does Dyness support say? Did you log a ticket with them?

Otherwise, there are two Dyness profiles on Powerforum, post and tag "Dyness Engineer Zhang" and "Dyness Engineer Weizhong".

They do respond as well... might take a few days but they are decent

I'd be hesitant to draw attention about going below 20%...
 
No the warranty spec is up to 90% so no concern there.

As I recall 20% is their longest life recommendation.

I did actually see those guys on Powerforum just didn’t feel the urgency to register just for this issue as of yet.
