Yeah I was going to mention india and lead acid batteries. They have a huge battery manufacturing industry. 15 years ago, I would say 90% of the lead acid battery market here were Indian brands, it’s probably now 60% Indian 30% CHines’s and 10% others. Indian batteries are highly rated here...

I wouldn’t extrapolate from one video on YouTube. i think you’ll find that countries with constant outages especially prolonged ones are up to pace if not ahead in terms of self generation of power and storage side. For many in the 3rd world the grid is the back up. Here in Nigeria, I have...

OK having reviewed this I now realize my bad. It wasn’t the OP‘s scenario I misunderstood but the explanation of houseofancients. When he said “no grid the sunsynk will shut down”, I now realize he meant the grid port will shut down not the entire inverter. Whereas I was insisting AC is AC...

We have frequent power outages here, so maybe there are some things we understand better than others because we have more experiences with blackouts and have instances with certain permutations or scenarios, as I type the national grid is down. In my home I have a 25kva diesel generator, I...

look my friend no need for the insults, i am here to learn, i am not here to trade insults. your initial comment was that “no grid, no ac coupling…. system shuts down”, now your shifting the goalpost saying oh it works in aux mode, you’ve been shifting the goal posts since. I haven’t got the...

See video above

You made a generic claim about off grid and AC coupling with hybrid inverters, I countered it. having said that it is the same principle at play with the Victron, they are both biderctional inverters, you could say Deye/sunsynk were designed to offer the functionalities of Victron sat a...

What I am questioning here is your assertion that ..and I am saying that conceptually and from evidence from others on YouTube and systems I have witnessed myself physically you are wrong. The microinverters are designed to shut down if there is no grid, I agree that’s how they are designed to...

Are you sure about this? From my understanding the sunsynk with batteries simulates a grid so the micro or string inverters will work because as far as they are concerned there is a grid! I think what you described only happens when you are running a system without batteries. The scenario...

Am I missing something here? I checked the specs of this inverter, it can handle pv of 4kw Are these figures you guys quoting over and above of the 4k? Because 2.75kw is if anything undersized.

so if I understand this 1. if Hoymiles micro inverters are coupled to a hybrid inverter with battery backup. 2. The Hoymiles with frequency shifting is set up for zero export to the grid. So even though it can produce say 5kw, there is only a 3 kw load from the home and so by my...

1. Am I right in assuming that this is not a concern in a zero export setup as the micro inverters would only be producing power required by the load attached to it.

I am also looking into Hoymiles but I am a beginner. From the little knowledge I have, the 450w panel will never actually deliver 450w. That is the theoretical power in the lab. The real life maximum power will be closer to 350w and that will happen only ever happen momentarily at the...

Thanks for that. I am a newbie so I’ll read up XHHW and THWN.

Out of curiosity can I ask how safe it is to run a dc line from a proposed solar car port to the main building in a low water table area? The property is built on reclaimed land In a low water table area. We are prone to monsoon rains which can go on for days at which times even after the...
