The Astronergy is connected to a stand-alone grid. A stand-alone grid is a grid which is not connected to a public grid ,the
Astronergy needs a grid-forming generator in order to function, The energy generated is consumed directly on site, surplus
energy can be stored in batteries.but the energy must not fed to the grid-forming generator. or it will destory the grid-forming
generator.
Alternative uses, modifications to the Astronergy PV inverter or the installation of component parts not expressly
recommended or sold by Astronergy are not permitted. Persons with limited physical or mental abilities may only work with
the Astronergy PV inverter following proper instruction and under constant supervision. Children are forbidden to play with
the Astronergy PV inverter. Keep the Astronergy PV inverter away from children.
DC and AC Switch
Separate the Astronergy CHPI KTL-M2 securely from the grid and the PV generators using DC and AC Switch. DC and AC Switch
shall be able to disconnect all unground conductors after installation.
Notes:
The Astronergy CHPI KTL-M2 include a DC switch ,if you turn off it when inverter is working , please waiting 5 minutes
to turn on it again.
Grounding the PV modules
The CHPI KTL-M2 is a transformerless inverter. That is why it has no galvanic separation. Do not ground the DC circuits of the
PV modules connected to the CHPI KTL-M2. Only ground the mounting frame of the PV modules.
If you connect grounded PV modules to the CHPI KTL-M2, the error message “PV ISO Low”.
