Now looking into getting the invertor online and then buying a new battery,

I asked the question of the BMS repairer: “I wonder why this growatt battery says 57.4volts, yet the Solax inverter manual says it should stop charging at 53.5 and start again at a minimum 47v ? ” David

He replied:
So, this is one of the reasons that these batteries are not compatible with other brands of inverter.Thery work at a slightly higher voltage than other brand batteries.The only way you will get this system working is to add a Growatt SP2000 to charge the battery or replace the battery with one that is compatible with your Solax inverter.Kind regardsChris

BMS first try: https://vimeo.com/1004760076

no voltage on the BMS output. The battery is showing 55.3 volts before the BMS

All of the packs should be within 0.2 volts of each other but ideally the closer the better. The BMS locks out if any of the packs is more than 0.2 volts higher or lower than the rest.

Also, if your SP settings are incorrect this can over time damage the battery.
Some installers change the settings to maximise the yield from the battery but this discharges the battery too low.
The settings should also allow the battery to be recharged to a minimum of 10% as soon as the PV is next active after a complete discharge regardless of home load

charging bad cell pack at 4.2v constant voltage

We have partially stripped down the old Solax battery and I am starting to get a feel for the job ahead. Last night we took the one flat cell pack out and started charging it via its neighbour using a 12v lamp at 5pm.

I think this looks a similar battery: https://diysolarforum.com/threads/darfon-gro-watt-gbli-5001-battery-pack-worth-a-punt.24226/

a mention of mucky terminals being a problem later on in the thread

7pm – the two cells I am equalizing are still not settled (lamp dimly glowing) funny how it takes so long

9pm – 3.8v & 2.6v  the  lamp is out now, but i’ve disconnected them, don’t know if taking the good one down too low will damage it?

Boston Power Swing 5300 cells

from this thread (the forum that I use)

a review on a different forumhttps://secondlifestorage.com/index.php?threads/boston-power-swing-5300-li-ion-cell-test.5188/

7 am next day – those two packs are now 3.9v & 1.8v, so I am beginning to suspect the BMS is faulty.

Connection Step:

  1. Insert the RJ45 terminal on the current sensor into the CT port on the inverter.
  2. Place the current sensor around the phase wire L which the inverter is
    connected.
  3. Place the current sensor around the phase wire L to measure the current
    going to or coming from the grid.
  4. Make sure the current sensor is installed in the right direction: The arrow
    on the current sensor must point to the public grid.

IR floods

PIR floods usually help but are not essential and dependent upon the position in relation to the camera can cause reflection and in some cases a 1 or 2 second distortion of the image as the camera switches from Night to day mode. I’d install the cctv and cameras first and see how it works both day and night before adding any additional lighting.
