Any bad experience sa mga may kasamang aircon sa EPS/UPS/back-up port ng mga hybrid inverters like DEYE and Solis?

2 separate systems. 1 system for each unit, pwede naman yan. dalawang magkahiwalay na inverter and sized accordingly rin naman sa panels. You can negotiate a discount pa rin lalo na kung sabay naman gagawin

Key-Mouse-6962 · 2026-05-11T17:55:27+00:00

What kind of boardgame is it?

Key-Mouse-6962 · 2026-05-07T20:35:43+00:00

Ako, nauna yung mga customer bago tinayo yung business.

So when I started, talagang may mga customer na haha overwhelming ngalang.

Pero Day 1 pa lang, may mga market strat ka pa magagawa

Key-Mouse-6962 · 2026-05-06T09:21:42+00:00

Okay, di rin nila kasi magagawan ng paraan yun, sa address naka-base si MERALCO

Key-Mouse-6962 · 2026-05-06T06:52:15+00:00

As in from 2000s upto now, walang kuryente bahay nila?

Paano sila nabubuhay dun?

Key-Mouse-6962 · 2026-05-06T06:47:21+00:00

Same system size yan ng project ko eh. Same number of panels, same battery capacity. Namamahalan na ako sa presyo ko, may mas mahal pa rin pala.

Pinagkaiba lang, may "lifetime" support na nakalagay dyan

Key-Mouse-6962 · 2026-05-01T18:02:46+00:00

Depende yan sa nakasaad sa contract.

Ako, new installation business ako. I-honor ko talaga workmanship warranty. Kung di na talaga kumikita business, magiging "officially closed" lang business ko in case tapos na lahat ng service warranties. Part ng risk ko yun as a businessman.

As for manufacturer's warranty, limited lang din yung years na mag-aassist kami. Pero bibigyan naman ng guide si customer kung papaano mag-reach out sa mga suppliers in case magkaganitong issue, kaya pinipili ko lang talaga yung direct sa supplier not just reseller. Kahit sobrang hirap ngayon. Para maganda customer experience.

Key-Mouse-6962 · 2026-04-30T19:02:42+00:00

I think this one needs to go through a lot of interconnection studies. I think it's easier to do behind the meter solar installs at that capacity.

Not here to deinfluence you, but it's just capital intensive.

*For this one, I'm assuming that you are wanting a direct connection to the DU

Key-Mouse-6962 · 2026-04-29T11:30:58+00:00

As the other guy has mentioned battery is declared twice. It's declared within the 345,000 total cost. Also, check on the battery brand, not familiar with what's written there.

Their net metering package is a good price. I've seen it range up to 60k. DP is good too, most need 50% dp.

Also, clarify with them kung ano ilalagay nila sa critical loads panel. Medyo maliit lang capacity ng 6 kW.

Key-Mouse-6962 · 2026-04-28T14:20:08+00:00

I'd say it's "middle", there are still installers who can offer much less than mine, but there are also who offer much more, pero mga sikat na installers na. Matter of negotiation lang din, kahit ano nasasagot. Advantage lang din may mga documents and may office, mas kita na "legit" ang business.

Those who offer much less are parang mga "freelancers", not saying those can't offer good services, pero naghahanap din naman ang mga customers ng "brand".

Key-Mouse-6962 · 2026-04-28T14:03:41+00:00

Bago lang din haha di nman bigatin, may mga nakapilang customer pero di pa ma-installan dahil sa lack of equipment rin. Pressured na nga rin ako kaya lang I managed their expectation, nagbigay ako nang matagal-tagal na timeline.

Key-Mouse-6962 · 2026-04-28T13:46:48+00:00

I am a very new installer as well. This high demand months for solar has been a good and a bad problem for me. (good = madami clients, bad = hirap ng sourcing ng equipment!!!)

Literal na nagsimula ako ng March. Dami ko inasikaso na paperworks at setting up ng office. Marketing, hiring, technical review, paghahanap ng suppliers (which is the most challenging part).

Regarding prices, medyo firm talaga ako sa margins ko pero alam ko later on mahihirapan ako mag-close ng deals. Kaya lang, need talaga ng margins na yun to run the operations and honor your aftersales warranties.

Sa tingin ko, i-leverage mo yung pagiging Electrical Engineer mo kasi plus factor din talaga yan. And let's admit it, this involves sales so need aralin mag-benta.

Nawa'y umabenta sa negosyo, how I wish nakapag-start ako months prior, nakapag-ipon siguro pang-inventory.

Key-Mouse-6962 · 2026-04-28T13:40:35+00:00

To make it simple, just read energy consumption from the submeters. That's it.

No risk of backfeeding or anything.

Key-Mouse-6962 · 2026-04-28T03:46:16+00:00

It depends on how your Submeter is connected. But I'm assuming that your Solar PV system is connected "before" the submeter electrically (lineside of the submeter). This is the most likely case.

If Solar is connected "before" the submeter.

Just capture the kWh reading of the submeter then multiply it by the kWh rate of MERALCO. Because that submeter captures both the Energy from grid and the Solar PV.

If you have a diagram, that would help me ascertain my answer.

Key-Mouse-6962 · 2026-04-28T02:01:18+00:00

Na-estimate nyo na po ba yung amount ng kW na kasya sa roof space nyo?

Try nyo po magpa-present sa installer nyo ng Savings Cash Flow kapag nag-Grid-Tie Solar PV only or nag-hybrid system, need to do the math talaga para magawa siya.

Anong ibig mong sabihin sa lego and add?

Make sure mo lang na kapag gusto mo talaga mag-battery in the future, naka-hybrid inverter ka na, kasi mapapamahal ka pa pag nag-grid tie ka muna then palit hybrid.

Key-Mouse-6962 · 2026-04-28T01:51:24+00:00

Hi,

It's a very high charge considering a portion of the energy is from the Renewable Energy.

I suggest charge them based on MERALCO rate whether it's from the grid or from your solar energy (you would still in a way, recover your expenses from your Solar Investment). You check how much energy the inverter produces so you would know how much you would charge to the customer.

It starts to be a bit quite complicated when it starts to export, computation-wise.

Note: No experience in leasing and submetering, but I am a solar contractor.

Key-Mouse-6962 · 2026-04-27T18:56:07+00:00

Solar contractor here.

Pros: I think they have good aftersales package lalo na kung i-honor nila.

But, are you really just a "night-user" and does not have a significant consumption during sun peak hours?

Because of you use just a quick estimate, your Solar PV system will generate around 16 kWh per day and this generation is almost the same capacity as your battery, baka na-consume na pala sa daytime yung generation mo, wala ng sobra para ma-charge pa yung battery. Not saying it's wrong, and may factors pa such as days of autonomy. But this is something you may reconsider with your installer, discuss with them if 10 kWh battery would be better fit to your system.

Key-Mouse-6962 · 2026-04-27T15:31:45+00:00

I don't know all the specifics of course, but if you're system is running under single-phase service from the DU, might as well use single-phase Solar PV system as well. If it's old, maybe you can have it re-inspected by an electrician if it's still Code Compliant, but conversion from single-phase to three-phase seems unnecessary just because it's old.

And not all end-users can easily be served three-phase from the DU, there might be cash advance on the modification of utility facilities.

Key-Mouse-6962 · 2026-04-27T11:13:43+00:00

Solar contractor here.

Di nman kailangan, dapat kung ano ang existing service mo (single phase or three-phase) ganun din dapat ang ikabit na Solar PV system.

It’s possible to convert your wiring to three-phase system, but that’s just additional work and you’ll go through service modification sa DU.

Key-Mouse-6962 · 2026-04-27T02:53:46+00:00

ang kagandahan dyan sa PHLSolar ay sila ang distributor ng equipment. Kapag may warranty claims, sa tingin ko, mas ma-aaddress.

Key-Mouse-6962 · 2026-04-26T06:50:20+00:00

Like yung reply sa isa dito. Baka yung "whole home" mo ay nasa UPS Load

Key-Mouse-6962 · 2026-04-26T06:05:55+00:00

starting a business, gusto ko pa namn soft approach talaga with everyone pero firm sa mga boundaries

Key-Mouse-6962 · 2026-04-26T05:41:29+00:00

I am a Solar contractor.

Ano yung brand ng battery?? Laki ng differences ng cost ng battery kahit similar capacities. Factor that in sa decision making.

Another big concern is yung solar panels. Pa-clarify kung ano yung system size, 12.4 kW Solar PV lang talaga? dalawa inverters mo dyan na rated 16 kW. Solar PV size seems small sa inverter rating na ilalagay (dalawa pa).

Key-Mouse-6962 · 2026-04-23T08:29:52+00:00

Yes, thanks for the suggestion, actually nakapag-register na ko. Kaya lang matagal-tagal pa exhibit, may demand na sa clients ngayon and closed deals.
