Change the “sparkie”.

Did you guys miss it? 🤣 https://www.news24.com/fin24/companies/eskom-warns-of-high-risk-of-load-shedding-for-first-time-in-over-10-months-20250131

The inverter, not the battery dictates the sizing of the wire and fuses.

You can get the Onesto brand for half that price. https://gmelectronics.co.za/pages/Our-Store.asp?PID=446264&P=160 AMP Double Pole Fuse Holder

Just get iPhones! 🤣

Hello guys, Please let's keep this thread clean of technical issues discussion and general chit-chat. I created this thread with the sole purpose of keeping track of the latest firmware versions as SS does not provide that.

Yes. The amount being drawn at the time. The inverter cannot determine spare availability. Ideally you should set this just below your house "idle" load. No.

Yes, your setup is more complicated. But I think, you should contact Deye support anyway and see what they say about the Smart Load when inverters are in parallel.

I'm currently on MCU: 3384-0513 E433 on my SunSynk 5kW and the Smart Load works as expected. I didn't have such issues with older firmware either. I've been running my geyser on the Smart Load for over an year and it switches on and off as expected. The only bug I have noticed, if Eskom is OFF and the battery is ABOVE the upper limit %, the Smart Load comes ON regardless of the PV power. Haven't had time to follow up on that bug with SunSynk support yet.

When you have "On Grid Always On" the "Power" and Battery % settings are ignored. With "On Grid Always On" switched OFF, then if the PV produces above the "Power" setting and the battery is between the specified %, the Smart Load Switches ON.

If they have been installed in a vehicle and that same vehicle has been certified in crash testing, there shouldn’t be much danger. Unless you maybe know something more than the vehicle’s certification authorities. I’m sorry but I’m still yet to see any danger from these NMC chemistry batteries, despite all the warnings from “Internet experts”. My Hubble NMC battery is happily working for 3 years now and no issues. There are thousands of NMC batteries installed all over Sourh Africa. Please point me to one dangerous incident with a verifiable report than the NMC chemistry alone is to blame for the incident . (Please no links to YouTube videos). Google is your friend.

What is the voltage of these modules and weight? Do they have built in BMS? Wonder, if they can be used as a secondary car battery - camping, etc.

How close are those CTs next to each other? Are they maybe not interfering with each other? If you space them a bit more, do you get the same odd readings?

This sounds like a bad batch. Do you happen to know the manufacture month and year of all those batteries?

As a matter of interest, how exactly did you measure the 20% more efficiency?
