How many days downtime? I read that other brand SAJ something also have many problem. I guess this fox and saj brand is basically cheaper inverter right?

Solar PV Insurance, got some info in facebook that the price is pretty cheap.

I am not considering the solar insurance for myself since it under the responsibility of emit solar for the next 10 years

I am assuming your inverter is hybrid type. Need to install ct meter and ensure the inverter has the option for ZERO Export

Mine is already equipped with this meter and ready to change to zero export at the end of nem 3.0

The idea is if the solar provider want to survive , they have to adjust their pricing to reflect the current ATAP scheme, you cant assume the solar pv provider to maintain at the same price as the previous NEM

Half hourly consumption is available in mytnb website but of course not in real time, but you get the historical data there

As to minimize the issue of importing in one phase but exporting in the other, this is where the inverter with load balancing feature play a significant role. It can be optimized to prioritize self consumption. I am mainly using only phase A and sometime phase b and c except when i charge my ev using a 3 phase charger



The system always prioritize self consumption and adjust the output on each phase based on demand. The graph above is showing current output from the inverter itself.


The graph below shows when there almost zero usage except for the fridge and some small consumption from multiple cctv and ups
All output spread evenly among 3 phases

Huawei sun2000-8k-mapo coming with compatible ct meter that can communicate with huawei inverter

The system optimizes self consumption based on demand and also to run zero export rule if required

I saw someone installed diy using chint dtsu66-hw from nem group in fb, iirc it is around rm600(shopee) for 3 phase, should be just a small fee even of you ask electrician to do the wiring.

Btw these are compatible list, but only some model support zero export

I understand that, but good thing is , i dont need a battery now. In 10 years when my NEM run out, i would either run on zero export or if huawei battery is cheap enough by that time install a battery or even change the whole inverter(non huawei) and install battery once the inverter breaks down

Yes, load balancing is good to charge ev using solar panel especially if someone is using a single phase charger but 3 phase inverter. unfortunately single phase output is still capped at 1/3 of max output of inverter

Recheck the calculation on the payback period, it seems the solar installer trying to kencing, no way 10kwp panel can save you rm750 per month

From 4 peak sun hour to 3.3 peak sun hour for month of november.
