I have buy parts and prepare to set up Push Button Pre-Charger On my 2 Inverters With Parallel Battery. The batteries are parallel connected between breaker and inverter. So i asking my self if enable the ONE pre charger if it will precharge both? Here is a plan i found ( my data is different from the example img) But i plan to connect it same way. Pink

Latest changes done and now its working, connecting all L ports in top was the key. Thanks to all who contributed. Pink 334166303_6310060529058176_39950617100528018_n.mp4

Ok, i will re wire all and also be sure use 3 pole connectors so all connect correctly. Update will come later Pink

Tested it now after change the wiring with no changes. My testing is with 2 pole connector so how it connect N to what house power wire is random.

Tested, no action Pink

Ok i will test that, thanks Pink

I see some other ATS connect to those green connectors: example Pink

Here it is Pink

ok, where i find that? Pink

Here is details from the top part. Pink

I have no manual. There is some info on lazada. Pink

Today im testing out the ATS before prepare to mount it up. I connected 2 wires to house grid power as 2 power sources and outpower to a light. All working when turn switch myself but there is no auto switch happening. When i remove the active power source it just close the light. Any ideas whats wrong? Auto/manual option is set to auto.

I did notice that, thanks, yes its typo. I have requested it to be edited if possible. Pink

Whole order was USD 4051 for 32 batteries and 2 x bms ($206) included delivery ($485) and custom etc. Pink

Here is a short update: I tested some batteries, all had same voltage as printed on the batteries: 3.28V. In photo is also the nuts and busbars who come with the batteries Pink

I easier to trust in a company who already have their name out there and who will have some efford to protect their reputation. Pink

This is what i based my decision on

Just got this back from Crossy: Pink

Photos sent to Crossy. Pink

My plan is to just put them up with the active balancer JK BMS. I expect they come with very identical voltage, but i will test that more later. I dont have any way to check if they already balanced. Pink

I see the qr codes in top of the batteries Pink

Hi.. I buy from QSO, i will ad some contact info very soon. All packed out now and look great.. No duty no vat.. I will get some more photos soon. Here is the 2 x 150 A JK BMS with 2A balancers Pink

32 x QSO LF280K arrived this morning. Just started unpacking. Until now all look very good condition. Delivery was just over a week from China. Pink

If anyone want to demand a theoretically correct ROI calculation is also need to the alternative earning of the investment (interest etc.) and also estimate future power prices and also inflation. Regarding EV, i guess some got more into EV options when discover the solar opportunities. Cheers for everyone who go solar route.. Hopefully money come back in reasonable time.. Let me also add that batteries maybe not give best ROI, but before i went solar route i was considering buying aggregate for emergency power. I would be VERY happy to have my ow backup power when grid down. Pink

Back in the eighties when i was a kid i had my charity workday in the senior nursing home my mother worked. At a time joined the male caretaker around the building then we get down to the very basement with the elevator. So i waited outside the elevator when i got something from one the rooms in the storages there. So im standing there with some keys and a screwdriver in my hands, then i noticed on the wall outside the elevator door there was 2 round metal items who looked like some kind of buttons, but they was level with the wall. I imagined this could be a priority button for elevator to come to me first so i got the key and screw driver and pushed in the 2 buttons. I got the shock of my life, it hit me so hard. What i pushed was the emergency poles for the elevator who is used if lost power and elevator stuck between 2 floors. later someone told me its quote much power in those old heavy elevators ant that i was very lucky to survive it..
