Hello Community,
How compact can a 9000VA 3-phase ESS system, including 10kW/h batteries be?
I tried to find this out :o)
5.1kWP of solar (15pcs. 340WP mono) panels will feed the Fronius (3kWP,9s,1p) and the Smart Solar MPPT (2kWP, 3s,2p)
Four big 230V AC powered fans are mounted on the top, to do ventilation and to get the heat out, they are not even very noisy.
I am still waiting for the battery pole covers and a 19-inch rackmount 8-way Schuko distributor socket, to arrive. The distributor should cover the wooden plate underneath the batteries
Excess PV power can be used, to heat water by 48V DC water heating elements. The 48V-100A Battery Protect is there, to switch the water heating elements on and off, so no danger of melting relay contacts exists. The BP is controlled by the BMV relay and the Smart Solar MPPT relay. I have no best practice ready yet in winter. However, first tests proof, that I have a good solution.

RGB LED strips on the top, light the cabinet’s internals.
A Wi-Fi capable RGB LED controller powers the strips. It is possible to change colors on SOC, active warnings and alarms, etc. via Node-RED.
To make this happen, install the node-red-contrib-magichome node.
Information, how to get Node-RED running on a GX device can be found here: Venus OS Large image: Signal K and Node-RED [Victron Energy]
This is how the LED’s are controlled in Node-RED:
I want to create a more practical control logic for the excess PV water heater too, but for that I need better sunshine to do tests.
If there are questions about details, I am happy to answer them.
Best Regards,
Markus
