Home system and hot water control

This is my home system in its current configuration.
I fabricated the battery bay but the equipment bay is standard 19".

I made a hot water controller which reads parameters from the CerboGX over MQTT and then adjusts the heating power accordingly. The PCB is designed to drive the water pumps and control their speed by a PWM signal. It also hosts the RaspberryPi which just runs Node Red.
There are four SSRs behind the PCB box which allow for six power levels.
The contractors are interlocked with a change over to switch between inverter supply or network if absolutely necessary.

Impressive Warwick, and a blue cabinet too! Maybe I should give my cabinet a paint job as well.

Hi @wkirby, Nice work, what is the device that is between your 2 US3000C blocks?

Hi @maa, that is just a passive feed through panel that I made for the cables.
It has the four SurLok connectors, a Canbus data connectoin and a few terminals for grounding on the left.
Behind the panel, the cables go out to the system.

Great system. I’m curious how you connect the dc cables.
