Good evening. Those with JA solar panels 575W

How much energy do you get on average

Boss. Please I need your help ooooo. I need una help o. I hit low voltage cut off for the Haisic 25.6v 8kwh battery and now my battery just shut and wont start. Does not come on. Power from grid wont charge it. Please how do I wake it up 'MANUALLY' like you said. Please Bro. I nor knw say this thing once e reach lvd go shut down totally 🥺

I know you have sorted this out now but just putting this information out here.
Not ALL inverters are smart and able to automatically wake a sleeping BMS. And nothing is wrong with the BMS of your battery by the way.
Settings on your inverter should be changed to make the LVD ( low voltage disconnect) to be about 1.5 to 3v higher than the Low voltage shutdown (LVS) of your battery. So for a 24v system if battery LVS is 20v, set inverter LVD to 22v. Mine is even set at 23.5v!
Other options:
1)Better to buy batteries with smart (Bluetooth)
enabled) BMS. You should still be able to communicate with it despite a output shutdown and wake it from the app on your phone
2) Get a AC Lithium external battery charger for such occasions. Need not to be expensive or of high ampere. Just enough to wake it
3) Get a external CC that is solar powered ( some newer Felicity cc do that for example) and once the Sun is out , wakes the battery. Most CCs are battery powered and will not work. So you have to look for CCs with that capability.
4) You may need to wake the Battery by connecting a similar voltage battery in PARALLEL to your battery.
5) Worst case scenario: On one of my setups where I could not alter the LVD of my inverter. I quietly connected some old Lead acid batteries in parallel to the Lithium battery pack. This ensures
that the Cc will be on even if the Lithium battery BMS sleeps and once sun comes out charge from the CC will wake the battery. Two years running and no issues

I don't know about external charge controller but most hybrid inverters would wake a sleeping BMS

My Bread inverter did when I first drained battery to zero to activate the BMS.

Everything went off, both battery and inveter, the first sunlight the next morning immediately turned on the inverter which then waked the BMS.

Normally, a functional BMS ain't supposed to allow you drain the battery to such extent

Exactly my thoughts.
Me no kuku dey used them for personal reason. An active balancer is enough. What is it now it managing? A 12v battery cannot shut down at 10.5v (LVD of most dumb inverters). At 21v for 24v system, it shouldn't .

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.

Hello house, please i have a 2.5kva indian inverter system that has no settings for Lithium battery, does that mean i wont be able to use lithium batteries with the inverter?

Also, it doesnt have any manual settings to change or adjust the voltage since the preset buttons is only for tubular, gel, sealed lead acid batteries only

Yes it means you can't use it for Lithium battery, except you intends destroying said battery.

But all hope ain't lost, just buy a compatible charge controller which has such a setting and You should be fine

Thank you very much, i have a felicity charge controller of 60AMPS, but then again, it means i can only depend on the sunlight for me to charge the batteries

You can also get a stand-alone AC charger for your Lithium Battery. So you now have a CC and AC charger to charge your battery at once; if there is no sun, you can use the charger and vice-versa.

UPDATE

So as adviced here, draining the battery TILL BMS SHUT DOWN is the needed trick to unlock the restriction that came with the BMS. Now battery gets full to user set value.

Thanks for the wealth of knowledge shared freely here.

There is this 60a mppt than can take up to 230v voc n are within 160-180k range. If u don't av the powmr 140a CC budget

Just found it's cousin in my friends house. It's a generic charge controller that different companies stamp their brand names on it.
Looks and feels subpar. I Will observe performance, though sun has been very absent coz of rains.
