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?

When you have an existing installation with COC and just adding couple of new plugs plus wiring on the essential side of an inverter, do you need a test report in addition to the addendum COC? And if yes, does it have to performed on the whole installation or only on the newly wired plugs?

Why do you need circuit breaker? Can’t you use fuses instead? It should be much cheaper.

I would say, even if not explicitly prohibited by the SANS standards, this is not a good practice and will be confusing even with extra labels. Rather put the indicators in a separate small surface mount DB.

I have been testing out lower than normal voltage for over 6 months now and I don’t see any negative effects. In fact, according to my research, most of the appliances should be better and last longer at lower voltage. I set my SunSynk at 200V output in island mode. No problems with any appliances so far and the geyser runs at about 2.6kW with the 3kW element, which give me more room for extra load during loadshedding without overloading the inverter.

From that article: “Although the list indicates that it is a recommended price, Victron, in practice, insists on a maximum discount from its recommended retail price list when the Victron products are sold to end customers by online stores,” How would that make Victron SO EXPENSIVE? It sounds quite opposite. Victron insist the most discount to be passed to the end user. It might piss off some resellers but at the end of the day, it's for the consumer benefit. The title of the article sound more of a clickbait or just plain bad journalism.

I'm waiting for Andy's and Will Prowse's reviews 🙂

Where exactly are they hitting the shelves? Link to anyone selling them today with current price?

Eskom just announced stage 6 as Black Friday special 😂

What Black Friday specials? Today is Thursday 🤣

If you want to downgrade I have the firmware from September 2021. It's still a version which shows 110Ah and not 100Ah. My battery is still fine with that firmware. Not sure, if downgrade is possible though.
