Hi Kevin I also have a Sunsynk with Volta Stage 1 Batteries, I am having an issue with Voltage charge discrepancies between the Sunsynk and Volta. Sunsynk sees the battery charge voltage as 56 volts, but 56 Volts on the Sunsynk is 56.3 volts on the Volta BMS, so this causes an over voltage pack alarm on the Volta every charge cycle.

Correct, Yes BMS Monitoring Software for PC.

Hi, I have a Volta Stage 1 battery. Looking for the BMS Software, anyone know where you can get the software.

I have a Luxpower sna with a Volta Stage one battery in operation.

You are correct, earth can be bridged /common.

I have a Sunsynk 5K, and every now and then get this F59 error wheb Grid power comes back after Load Shedding. Any ideas what cold cause this. My Inverter loads are never above 1000 watts. Thanks

👍

I have to agree with you on this one Tony, I got a 5k Sunsynk, and really regret not spending the extra for the 8k.

This is what have have installed now, working perfectly. pg2.pdf

You cannot bridge the municipal Neutral and Earth even if it's to a separate Earth Spike, this will cause an earth trip on your Mains. Neutrals on the inverter input and output are bonded internally in the Sunsynk in "Normal" operating mode, so you cannot put a permanent earth bond on the inverter output Neutral. You need to use a relay so the Inverter output Neutral is only bonded to earth in when in Island mode. Hop this makes sense.
-
Thanks, agreed. I have not installed the SPD's on my install as the Sunsynk already has internal SPD's. The relay for the eath bond is a must though to het rid of the floating neutral when in island mode.

Did you get your Daly BMS to communicate with the Sunsynk. Is it on CAN Bus, or RS485 ? What pinouts did you use on rhe inverter side ?

Thanks Tony, I came across this recommendation on the forum, and seems similar to your setup with the Inverter Grid connected before the Main E/L, so I'm going to give this a go. My house is old, and only has a combination OL-EL breaker wich is a 20 mA, so I will replace this with a 60 Amp OL Breaker, and a separate EL. Thanks for your response.

You say "In top left hand corner it show off" You need to push the power button to turn the inverter on. Just because the display is on doesn't mean the inverter is switched on.

So what are your battery settings ?
