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

Goodies arrived from Mantech.
One temp controller with 12v relay and some fans. Just waiting for the 3D printed brackets for two 5kw inverters so I can hook it all up. I'll connect the temperature sensor to the master inverter and figure out temperature ranges then set and let the fans run on thermostat.

The inverter provides internal temperature. Why not use that?

Could you provide the links to the kit you bought? I am looking to do similar with our inverter…

I've contacted two installers so far for a quote and one installer told me to rather go for Deye vs Sunsynk because "with the sunsynk the installer has access to your settings and some of them will mess with your settings so that you do a callout"
And they're not fans of Luxpower because they "have to many returns"

Very simple to kick them off and take full ownership.

Why not just run the fans continuously? Two 12V fans use so little power it isn't really worth managing them. They will also be almost silent.

I have done something similar on my 8kW Sunsynk, but this inverter doesn't really have any openings apart from the fan inlets and outlets on the other side. So I have mounted 2x 120mm fans with a printed duct to blow air over the inverter's inlet fans. I still need to add a filter on the new fans because there is already some dust buildup on the inverter fans. However, the airflow of the 12V fans are much lower than whatever noisy fans Sunsynk uses. They keep the inverter a bit cooler but it's own fans still come on when it is working hard. I have space to add a third fan as well but not sure it will help much as that will be on the lowest position. There are a few 12V fans with a bit higher airflow but still not close to what the Sunsynk fans seem to be doing.

This was the most expensive - I'm paying R500+ to print and ship but still well worth it for me.

You could substitute the fans with AC fans and get the AC equivalent of the controller. I got DC because the controller needs to be powered with DC anyway so I may as well use the same PSU to power the fans.

Might have missed it in your earlier posts, but what psu are you using to power this?

The fans he quoted are rated at 0,2A which is very low. I used 120mm fans rated at 0.07A. Both of these are easy to run off any 12V adapter. I used one of these:

That will be able to run multiple fans. Get a connector like this and wire the fans to it and the power supply just plugs in.

Awesome!

Please could you let us know how easy it is to set-up?

Will you be wiring unit into a plug?

Something I've been considering is battery temperature - seems like too much heat is an enemy of battery longevity (specifically the LFP, seems like the NMC's handle heat better).

Problem is, the battery units are sealed, so not sure cooling fans would have any impact?

I'm struggling to add my logger... app says "the logger has been added" but then I'm still not getting any data (and the logger isn't showing under Devices)

I didn't have to do any of that.

If you have a logger added to Solarman, just register a new account on Deye Cloud using the same email that you used for Solarman. It picked everything up automatically...

Glad it's more useful than the standard Solarman

Solarman Business still has more stats, Deye Cloud just has the better overview.

It's difficult for me to tell when the grid is down or not because my neighbours now all have solar, so I can't just look out the window anymore, so this helps.

Just biding time until I can get my hands on a Pi 4 to run HASS...

Didn't work for me :(
Did exactly that (it did pull through some info, but not the logging)

These things are like hen's teeth.

I ended up ordering a OrangePi from Amazon to run SolarAssistant, way too expensive for what it is but it what they recommend you run it on.

Not sure how much it costs on Amazon, but you can get an Orange Pi with Solar Assistant pre-installed from the Solar Assistant site. They also have the cable that you'll need.

Leaning towards Home Assistant with the HASS plugin because I'd like to automate other things around the house, and it'll work wirelessly without running cable to your inverter. They don't seem to support Orange Pi though (or maybe they do and I'm being thick), so will just have to wait it out for a Raspberry Pi...
