Does this mean inverters that support this feature ( can working without batteries) have the ability to wake a dead lithium battery caused by bms shutdown?

ask4bk:
That's just another feature that hybrid inverters may or may not have. Even external charge controllers come with this feature while others don't.

HeavenlyBang:
It's just terrible, really.



Of course they cut corners. Their 8kwh battery is only like 7.2kwh. Still amazing for the price, though, so I don't know why they just won't market it as what it actually is.

Overstating capacity is a Chinese thing.

They do this as you can't sue the people selling a product. Also regulatory compliance is not a thing in China. So not hard to see a 3000w rated device not handle 1000w.

I wish they'd actually state the real capability of device. But that's where reviews and research can help or even better DIY your thing.

dollarnaira:
The thing is price.
At times price is enough to tell us the value of purchased product. If 1litre of fuel is not true here,who are we to Judge judge China?

SaintUlot:
How would you have solar installation in your house and you are still spending money to buy cooking gas and paying for fuel to transport yourself? That is an abomination, you are obviously shortchanging yourself, if you ain't optimising the immense benefit of your home solar installation.

this one na for ongrid people.

ask4bk:
I no come understand you again. You just said a charge controller can't regulate high voltage whereas that's the primary work of a charge controller. This is funny 😁. All a charge controller does is to step down DC voltage to the voltage you set it to. It can receive 300v 12a and step it down to 12, 24, 48v or any figure you set it to, while it increases amps or regulates it accordingly. Every charge controller is a DC-DC converter.
You thought only battery can give 48v for eg? 🙆🏾‍♂️🙆🏾‍♂️.

Anyways.. I guess you've already figured it all out.

fuckboys:
Please chief what do you think could be causing buzzing noise from my inverter whenever it rains, but whenever everywhere dries out the noise stops. And the issue is coming from the pv cos the noise stops when I turn off the pv breaker.

And this only happens only when it rains and after raining.

mctfopt:
Everyone wants a great deal. I wish they'd be upfront with what they are selling.

CuteMaro:
So basically, an inverter being able to supply electricity in the absence of battery is not a guarantee for waking a dead battery in the case of a bms shutdown.

CodeTemplarr:
Thats likely Noise. Stray energy that enters along the normal signal that gives power. When the sun is intense the noise to stable power ratio is lower but when the deniminator(sun energy) becomes less due to rain and noise remains almost same. The ratio increases.

ask4bk:
When you succeed pls share findings and result with us since we all want to learn.

As for inverter that no one is using, we no get.
But if you wan pay for the inverter for the experiment, ehen, then that one we get inverter to give. 😂😁

bassdow:
you do know you mustn't use an inverter to wake a sleepy BMS right ?
Hopefully it's only sleeping, and didn't go into lock-down

Hello......

Most Nigerians don't have an option, it's either solar or nothing.

So, for now, it'd take a long time for that to be Nigeria's problem

Obnoxious2001:
Can't even be a Nigerian problem.

Some people do solar in Nigeria to reduce bills
Some for survival
Some it's a necessity

So Nigeria no get business with any of those things.

Now this now brings me to another topic, will solar systems owners be willing to pay for insurances for their solar systems?

gagzee:
Hello everyone, good day 🙌🏾. Please I need advice, on this product. Is it a good deal? And please any review s about the product would be appreciated, thanks🙏🏾🙏🏾

CodeTemplarr:
some are just mosfets. To put a solar pv on inverter as battery is an unstable and unpredictable arrngement. There has to be an SMPS inside between that step the DC to a stable output before inverter can easily turn it into a stable-enough AC.
