can connect a generator onto the grid side. This can be used to charge the batteries and supply the load
when the batteries have a low charge and there is not enough sunshine to the PV supply loads to charge the
batteries. The auxiliary input ‘GEN/AUX’ can be used to connect a generator. Please refer to the section using
generators.
IMPORTANT:
When using inverters in parallel mode, the generator port cannot be used. The reason for this is because
the inverter reverses when charging the batteries.
If you have more than one inverter connected together, then it causes a huge problem when one inverter
reverses and the others do not. Therefore, if using multi inverters that can reverse in parallel, you must use
the Grid Input to charge the batteries from the generator.
When wiring your AC connections, you need to provide suitable changeover switches and correct rating
fuses. Please refer to the local electrical regulations.

3.4. INSTALLING THE CT COIL
A 1:2000 Current Transformer Coil (CT-coil) is used to control the power export or the import from the
grid. The CT-Coil is one of the most important parts of the Sunsynk Parity inverter. This device reduces the
power of the inverter to prevent feeding power to the grid. This feature is also known as ‘Zero Export’.
