Total Ampacity of the Home 8 and PV Inverter is
≤
200A (Partial Backup
with the Main Panel)
1) The total ampacity of the breakers in the main panel should not exceed the ampacity of the main
breaker in the main panel.
2) The total ampacity of the breakers for the Home 8 and PV inverter should not exceed the
ampacity of the main breaker in the SE Box.
3) The ampacity of the main breaker in the backup panel should not exceed the ampacity of the
main breaker in the SE Box.
4) It is recommended that the PV CT be located in the SE Box.
5) In this case, external CTs are required to measure the site net metering. The additional CTs can be
purchased from LGEUS, and the installers must prepare these CTs ahead of the installations. CTs
not supplied from LGEUS may give the wrong measured value for site net metering.
6) The energy meter in the SE Box can measure up to 400A (2 x 200A CT). If the service ampacity
is greater than 200A, 2 x 200A CTs are required to measure the site net metering.
For example, in the case of 400A service, two 200A breakers are used in the service equipment.
Then 2 sets of external site net CTs are Required. Follow the instruction guide on external CT
installation.
