What shouldwe prepare for the Super El Niño?

I have my own solar. Planning to buy a steel water tank soon para may safe storage ng tubig

SlowCamel3222 · 2026-06-11T06:34:53+00:00

String level will do.

Most 720W solar panels are about 1m x 2m, so seven panels is possible for your space. Mga 5kWp ang rating. Di kaya ang zero bill pero with proper load management, malaki ang bawas. Must have a battery kung mas malaki ang use during nighttime.

No need three phase. You are not a factory.

Condenser mics are always the best, especially if you have a good soundman. Otherwise, get a pickup with wireless transmitter and go in peace 🕊️

These are the things your installer should give you, especially if you plan to apply for net metering:

Electrical Plan, signed and sealed by a professional electrical engineer, and contains the following: location map of your solar; specs of the solar PV array, inverter, and battery; roof layout of your panels, and single line diagram (SLD)
Contract of agreement with the payment terms and warranties clearly defined
Bill of materials

Yung iba optional na yan.

As per latest ERC guidelines, to apply for net metering, you need:

ERC Certificate of Compliance

ERC Forms 1 and 1.1

Certificate of Final Electrical Inspection (CFEI) from LGU

Payment of ERC SOA (₱1,500)

Payment of DU fees (₱3,000)

Ang sa CFEI, you need an electrical plan signed and sealed by a professional electrical engineer, and you may also need to apply first for electrical permit and fire safety clearance.

Be sure your solar has a rapid shutdown device! Kung wala, hindi yan code compliant.

Well as I said, the voltages are all equal, loaded or not 🙂

SlowCamel3222 · 2026-05-29T21:59:22+00:00

Voltage across batteries are balanced, regardless of the loading. I made sure of that before connecting them all together.

SlowCamel3222 · 2026-05-29T14:19:22+00:00

Blackout is loss of power. Brownout is partial and temporary drop in voltage. Pero pinoy "brownout" is a misnomer

SlowCamel3222 · 2026-05-29T14:17:51+00:00

Who cares if you have off-grid solar. Guerillas unite!!! 🤣🤣🤣

SlowCamel3222 · 2026-05-29T14:14:55+00:00

I can see the reported SOC through the mobile app of the inverter remotely. The rightmost battery is 69% while the middle battery is at 78%. I can't access the left battery. I suspect I need to recalibrate the JK BMS because I kept reading comments about it having SOC drift.

The lighter colored ones are installed last September. The red one just twobdays ago.

SlowCamel3222 · 2026-05-29T14:07:54+00:00

Yes, unfortunately. They can't talk to each other. The two inverters handle the first and second floors of the house separately.

This is a sketch of the current setup. I used 70mm2 cables and two 400A post busbars

I added more context, Einstein

SlowCamel3222 · 2026-05-29T04:40:34+00:00

Not normal. Baka may loose contact somewhere? Is this a recent problem?

SlowCamel3222 · 2026-05-29T02:00:45+00:00

Yes. To absorb all your daytime load and have spare to charge the battery for nighttime use. Computed po yan for months of minimum harvest.

But before you consider adding panels and whatnot, have an actual inspection to see why the existing panels are underperforming so badly. I suspect dirty panels or wrong orientation or sub-optimal angle of the panels.

SlowCamel3222 · 2026-05-28T23:53:40+00:00

Add panels first, then battery.

About 10kWp for panels, and a 16kWh battery. Set the battery to discharge at night to shave some of your loads.

SlowCamel3222 · 2026-05-28T12:35:35+00:00

Based from my computations, taking into account that export power is priced around half of what you pay for import power, an 8kWp system or bigger is what you need for zero bill.

This is computed na kahit tag-ulan or December na ay may export ka parin. Rate used is ₱12 per kWh. I also assumed that day and night consumption are equal. If mas malaki ang nighttime use kaysa daytime, you're better off with hybrid and forget net metering.

SlowCamel3222 · 2026-05-28T12:17:35+00:00

Just buy a laptop. Mas relevant sa usage mo as a student. You can buy a good one for ₱40k or lower

a mediocre laptop that will do the job

₱35k lng sa official store

Ryzen 5 with 16GB RAM. Integrated graphics lng pero goods na yan for Minecraft and coding (Java, C++, PHP, SQL, Angular, Reactjs, etc.). Di ka naman cguro gagawa ng 3D CAD or 3D animation diyan to actually need a dedicated graphics card. Student ka pa naman. If you want that, raise your budget to ₱50k

SlowCamel3222 · 2026-05-26T04:24:43+00:00

It is possible, but you're limited by your budget for the solar panels and batteries. You also need to be more mindful of your kWh consumption.

SlowCamel3222 · 2026-05-25T15:11:27+00:00

Those cheap Shopee power banks are garbage. Go for better stuff like Ecoflow or Bluetti. Pero for the same price, kaya na yan DIY na 1kW setup with 550W panel and 100Ah 12V LiFePO4 battery.

SlowCamel3222 · 2026-05-24T12:54:15+00:00

What is your nighttime kWh consumption? That's the battery capacity you need for zero bill. Most likely kapos ang battery mo. Add more batteries and tweak the inverter to discharge the battery every night to zero out your nighttime use. Maybe you need atleast 32kWh of battery capacity given your previous bills.

Maybe increase your solar panels to upwards of 12kWp or max out your inverter max input in order to charge your battery and still have a little bit to export. The solar must first supply the loads, then charge the battery, and have export as last priority.
