This is tricky. My installer / electrician were adament that the huawei inverter and solarmax hybrid cannot be on the same KE line. Fortunately I had a separate KE connection to which I added the hybrid inverter (zero export turned on as I do not have a net meter on the second line / KE does not support net metering on single phase inverters). When the grid turns on, the load is removed from the hybrid inverter and the panels only charge the battery / no load sharing.
At time of power outage, the hybrid inverter solely powers the house coupled with the 2KW panels and battery. My electrician has made changes so that only a reduced load is powered by the hybrid inverter automatically instead of running and turning individual devices off.
My idea was to create a generator substitute (i have an aging 20 year old generator powered by natural gas, which itself isn't available at most times). While the ROI on the hybrid inverter doesn't make sense, the convenience and comfort offered is close to none. During the lengthy power outages exceeding 6 hours +, my entire house was running with all essentials.
Just a quick cost of the hybrid setup towards end of sept (inverters are super short now, I'd say more valuable than gold and the mighty dollar) was close to 8 - 8.5 lakhs (I had a higher cost due to lithium battery).
The above write up is only for people with existing on grid setups that need an additional hybrid inverter for load shedding - otherwise it is best to invest in a high quality hybrid inverter (could cost twice as much as an ongrid) thereby eliminating the need for two separate inverters.
Hope this helps!
