10KW Sungoldpower hybrid inverter errors 59/30

[Azydo]

I have a 10KW Sungoldpower hybrid inverter (SPH10K48SP) along with 2 X 48V 100AH Server Rack Lifepro battery SG48100P solar system. Inverter AC input is fed from the main panel. Inverter AC output is feeding a subpanel. I have the inverter setting 01 at SBU, which indicate AC out source priority to Solar then battery then utility. Setting 06 is at CSO for battery charging mode. Yesterday night, both batteries were showing 6 solid green lights indicating full charge. I connected my EV charger to charge my car over night. This morning, the car was only partially charged and the inverter screen is showing a warning with fault code that keeps switching between numbers 59 and 30. I'm hearing a ticking sound every now and then coming from the inverter with the screen keeps showing the batteries supplying power to the house then the screen switches to show the grid/utility supplying power to house . My BMS is connected between batteries and from battery 1 to inverter in accordance to the video posted on sungoldpower official youtube channel (

). I assumed that the inverter will switch to using the grid power to feed the load instead of batteries when they go low in power. Thanks for any help.

I'm hearing a ticking sound

I think this sound happens when the unit changes the power source e.g. from battery supplying your house to grid supplying your house.
There are settings that determine how far the batteries are allowed to be discharged.
Once this threshold has been reached, they need to be recharged from solar panels (you did not mention that you have any, but I would assume you do??) or from grid.
Once a certain threshold has been reached, it will allow discharging again.

These thresholds can be specified as voltage points e.g. "stop discharging once it falls to 48V" or as a % number (state of charge, SOC).
The % number can (should?) only be used when you run in closed loop with the supplied communication cables. I believe it is more accurate than the voltage thresholds.

You don't want these 2 thresholds to be too close together e.g. 48V stop discharge, 50V allow discharge again, especially if you use the blurry voltage as measurement.

The SOC specific settings are 58 through 62.

Yes, I have solar connected.
If batteries are below the threshold so they no longer supply power, shouldn't the inverter automatically switch to grid supplying power to both the house loads as well as recharging the batteries? if the answer is yes, why the ev was only partially charged?

Again, thanks for the help.

I have (almost?) the same inverter.
Mine is a year old, may be older firmware.

Error 30: Battery SOC below 10% alarm (Only enable BMS take effect)

Error 59: not listed in my manual


I think error 59 should be identified

Possibly the EV stopped accepting a charge when there was something going on. Did the EV report anything?

My PHEV once switched from 12A to 8A because it had sensed a damaged wire (warm plug). That was with level1 charging, with an extension cord.

I had accidentally driven over the cord and caused internal damage. The PHEV recognized it. That cord is in theory still good for skill saws etc. Just not for ongoing load like car charging.
