This page explains the steps needed to make the initial configuration for a ES-Micro system. Normlly this will be done before you as an end customer receive the equipment.
FIrst, we must have a specially configured CSSB where a Shelly 3EM has been installed on the input side. Some of the AC 220 sockets will be used to connect micro inverters, the others will be used to simulate the consumption of a house.
A laboratory charger (30V, 10A) with the ability to regulate voltage and to limit current will be used to feed DC energy into the micro inverter.
The AC side of the micro inverter is connected to a plug in the CSSB via a Switch. This allows us to connect/disconnect the AC side of the inverter easily.
A small resistor between the DC power supply and the inverter is used to simulate the behavior of a solar panel. This means that the voltage will go down a little bit if the inverter draws more current. The charger delivers 30V, the resistor has 3 Ohms.If we want to have 5A at 25V and
A lamp (20W) is connected to another pug of the same phase via another switch. A second lamp is connected to a different phase. This allows us to simulate changing loads.
