Thanks - they look excellent and a very good size for the capacity.

Yes, this is my currently company do
Offering the plug and play battery for customer

Richard's battery is with heated function
And also WiFi connection via phone

Price will be higher than DIY project also
But it will worthy it

Enjoy the power

I'm still waiting for the muscle to arrive to help me move them, but after opening the top crate, first impressions are they are very well packaged/protected inside

Pics below for now, more later:

Managed to get them into the house!

All powered on and seem to be fine, will try to connect to WiFi and report back later or tomorrow.

Connected to the batteries with the app:

Temp, voltages, etc seem fine.

Was having a look at the battery ports and connections. Still a couple of weeks away from installing, but was trying to get my head around where everything plugs in, etc.

Seems straight forward connecting in parallel with the communication cables...
RS485A slave battery <-> RS485A master battery
RS485B master battery -> inverter
(From manual)

I was thinking (stupidly??) that the power cables would connect to each battery as well...
P+ slave battery <-> P+ master battery <-> P+ inverter
P- slave battery <-> P- master battery <-> P- inverter
But there is only 1 P+ and P- on each battery.

So I assume both batteries power leads just connect independently to the inverter and the batteries themselves are only connected to each other by the RS485 cable?

P+ slave battery <-> P+ inverter
P- slave battery <-> P- inverter
P+ master battery <-> P+ inverter
P- master battery <-> P- inverter

Will the inverter be able to accept 2x cables to each of its P+ P- ?

Just thinking out loud at the moment... Maybe creating issues that aren't even issues. Just thought I'd ask you guys in here before hassling Colin by email! Cheers.

[Richard77]

The more I think about this, the more I think there should be two P+ and P- connections on each battery?

[Stinsy]

I'm assuming it is a current thing! IE there is too much for one set of cables / connectors to handle therefore each pack needs its own cables going to a bus bar.

Use a common bus bar so only one connection is required..

[Richard77]

No idea... I've fired an email over to Colin.

Hopefully it won't cause an issue and I will still be able to connect them in parallel to get the full 30kWh and to the inverter.
