Need to connect 2x SolaX gen.2 chargers to your SolaX inverter?

The new SolaX gen.2 chargers support data interconnection between each other to share information about the transfer point.

A prerequisite for this parallel mode is to have the same power variants as well as FW version 1.12 and above.

Wiring diagram:

1. Connection variant directly to the inverter

The data chargers are connected via the green terminal strip located on the bottom of the charger near the power contacts as follows: from the primary charger (which is connected to the inverter) port RS 485-2 A + RS485-2 B to the secondary charger port RS 485-1 A + RS485-1 B. The primary charger is connected to the inverter either via RJ45 port or via RS 485-1 A + RS 485-1 B. The wiring diagram looks like this:

2. Connection variant with CT

Také lze připojit k nabíječce její vlastní měření a řídit dle primární nabíječky i tu sekundární. Na primární nabíječku se připojí vlastní měření buď do RJ 45 (pro CT nebo elektroměr) případně na RS485-1 elektroměr.  Nabíječky mezi sebou se propojí následovně: z primární RS 485-2 A + RS485-2 B na sekundární nabíječku na port RS 485-1 A + RS485-1 B. The wiring diagram looks like this:

Setup:

The setup is done only on the primary charger as follows:

Parallel function – ENABLE

Power ratio: 1:1 (Note: This is used to divide the power if both chargers are running at the same time and the mains capacity is exhausted.)

"The functionality of the two chargers in parallel mode is as follows: The secondary charger copies the set mode of the primary charger."

Newly added to the SolaX hybrid G4 inverter is a function for modifying the logic of emergency disconnection of the inverter from the grid known as the SHUT DOWN function or 0/100% regulation. There are now 3 modes to choose from:

1. Battery and inverter power disconnect function

When the potential free connection of pin 1+2 on the COM port is made, the battery / BMS master contactor will be disconnected, thus disconnecting the battery system from the inverter and also forcefully disconnecting the inverter from the distribution network.

Setup as follows: advanced menu - shut down - function control - use COM

Wiring:

2. The function of forcefully disconnecting the inverter from the grid, keeping the battery charged

This function is located on the SHUT port of the inverter and pin 4+6, when these pins are connected potential-free, the inverter is forcefully disconnected from the distribution network, but the battery charging function is maintained.

Settings: advanced menu - shut down - wait charge mode - Enable

Wiring:

3. Inverter power disconnect function from the mains, no battery usage

This function does not need to be set in any way in the inverter, and is active by default on the SHUT port and pin 4+6 in a potential-free connection. When this function is activated, the inverter is forcefully disconnected from the distribution network and also does not charge the battery.

Wiring:

External ATS function

If you want to have the EPS output of the inverter always under voltage, please set the External ATS function to Disable in the Advanced menu.

Do you own a SolaX inverter and are unsure which Dongle for communication is compatible with it? We have a solution for you!

Remove the protective cap from the Dongle connector and check the shape.

1) If you find a recess with a USB port, then the type of WHITE Dongle Pocket WiFi 2.0 - order code (B-210-1000) is suitable for you.

2) If you find a black plastic extension with a USB port, the BLACK type Donglu Pocket WiFi 3.0 is suitable for you - order code (B-210-1014)
