Battery Settings

Featured Replies

Hi all,

 

I got a 5KW Sunsynk inverter and 2 X 5.32 Sunsynk batteries 

 

I would just like to verify the installers settings as im also learning the in's and out's

Im mainly concerned with the following:

Looking at the spec sheet the nominal rating for charge/discharge is 0.5c or in other words 50a?

So because i got two thats why its double right?

Now will it be beneficial for the battery to just change the charge and discharge to 100a?

Lastly i have seen the battery discharge at 5.3KW 5300W at some point when i was using the stored energy from the panels max discharge is 5000W according to the spec sheet, should i change it somewhere or is it good?

If everything is connected correctly then the BMS should manage your charge and discharge settings automatically. Having said that:

Yes its double because you have 2 of them 

Typically you want to charge at less than the max so you CAN set the charge + discharge amps to less than 0.5c

So is this correct then right?

You think it will be beneficial to set it to 100 and 100. Maybe extend the batteries life a bit and keep them healthy?

If you select the LiBMS menu on the inverter what do you see? 

No harm in reducing those values - i have mine at 120A and i have 3 batteries so the system could in theory work at 150A
