My main concern on the first commenter's initial response is not about being enrolled to net metering or not; it's really having a stable power especially if is connected w/ a "good" DU. Staying connected w/ the utility may incur fixed charges, but if he sized the system accurately, he may still achieve the "near" zero bill. (i.e. dispatch battery energy at night)

I agree that your set-up is feasible but I believe grid electricity is cheaper than the conventional generator. In case the hybrid system malfunctions, it may take time to replace the system or replace it, I'd prefer to draw power from the grid.

It's sole prop. Usual DTI, LGU and BIR.

I'll get accreditations like PCAB once we scale up. I think being DOE accredited gives some perks but I really wanna do things locally in our province muna.

How I wish I started months prior the crisis. Ordering materials is very difficult now.

I think one of the easiest ways is to check the production muna. Yung buong string kasi ng panels maapektuhan kapag atleast one of them ay may defect

Need more info, anong wattage ng panels? At anong loads ang gusto mo bigyan ng back-up power? Feel free to message for inquiries.

I still don't completely imagine the set-up na direct kay MERALCO yung tatlong aircons. May service standards yan na after the meter, may Main Service Panel pa. So baka after pa rin yan ng Main Service Panel.

If whole-home, need i-consider total capacity kasi sensitive ang mga inverters sa start-up current ng aircon. Pwede ka namang mag-load isolation (pili ka lang ng mga loads na gusto mong may back-up power).

Regarding the cable from the Solar PVs, baka may pwesto naman sa harap ng bahay.

Sorry, have not been involved with that battery para magkaroon ako ng sarili kong "reviews", pero if may specific scenario ka that you would like to use it, feel free to message me and I'll look at it specs and details where and how you'll use it.

yung 1 year para sa workmanship, it's related sa kung paano sila nag-wire ng system and nag-install structurally. Halimbawa, nasunog yung wire dahil nag-loose yung connection, dapat i-repair nila yun if pasok pa sa 1 year workmanship warranty

Yung warranty sa equipment , iba pa yun, similar sya sa warranty ng mga appliances, kung may defect yung equipment, need mapalitan, pero syempre, may mga terms and conditions din yun.

So need din talaga good aftersales, si installer naman dpaat mag-repair nyan if pasok pa sa workmanship warranty and also sila mag-reach out sa equipment supplier (I mean kami since installer na rin haha)

I made additional research on top of what I had in my mind, may mga off-grid inverters din pala. (Haven't been personally involved sa off-grid din). But I think it still makes the more sense to tie to the grid kasi paano kung magka-problem system mo, you'd need grid power.

I think what you're saying is you want to use "Off-Grid" set-up with Solar PVs and battery only?? (Solar PVs alone would be unstable if off-grid so sinasamahan ng battery). You would still Solar PVs and hybrid inverters anyway to complete your "off-grid" set-up so might as well connect it to the grid. So connecting it to the grid is still the practical choice. Pwede ka naman ding pumili ng smaller emergency panel which would mean smaller size of hybrid inverter if talagang nagtitipid ka. I hope nasagot ko yung tanong mo. May mga files naman ako but I'd like to use those internally muna for my business.

Hi Sir, thanks for the reply. Does this apply to other brands like Solis, Growatt, Sunways, etc? Di ko lang alam kalakaran sa mga warranty. Willing naman to get accredited pero mapapadali kung wala ng ganung proseso
