JH Solar: All-in-One Solar Systems and Solar Setup Help for Philippine Homes

What JH Solar Offers: Two All-in-One Solar Systems

JH Solar is a solar brand for homes and small businesses in the Philippines. We offer two all-in-one systems, Version 1 and Version 2, and help you work out which one fits your daily use, if either does. Both units are rated and priced below, so you can compare them first. You may also see our name written as one word, JHSolar; it is the same brand.

What all-in-one means

An all-in-one unit puts the hybrid inverter and the battery in one cabinet. The inverter turns DC power from the panels and the battery into AC power for your outlets, and it manages charging from solar and from the grid. In a system built from separate parts, these are two or three boxes on a wall joined by heavy cables.

In an all-in-one, the main link between inverter and battery is made inside the cabinet, so the install is neater. It does not remove the rest of the system: you still need panels, mounting, PV cables, breakers, surge protection and grounding, all installed by a licensed electrician. The diagram shows how the parts connect.

Solar panels connect through a DC isolator and surge protector to an all-in-one unit that holds the hybrid inverter and the battery in one cabinet. Utility power feeds its grid input through a breaker, and its backup output feeds the essential-loads panel.

• Benefits: one cabinet, a tidier wall, fewer site connections, and an inverter and battery chosen to work together.
• Trade-offs: a fault inside can affect the whole cabinet, adding battery later depends on the unit, and the cabinet is heavy, so it needs a solid, ventilated spot.

Version 1: the smaller package

Version 1 is rated for a 7 kW inverter (230 V AC, pure sine wave) and a 16.38 kWh LiFePO4 battery (51.2 V, 320 Ah). Its one MPPT solar input takes up to 4,480 W, so it works with up to 6 panels: 6 × 620 W is 3.72 kWp. The unit price is ₱120,000, unit only, and the warranty terms are written into your quote.

One honest limit: 4,480 W of solar input cannot fully refill 16.38 kWh in a short peak-sun window, so Version 1 suits smaller daily use and night backup. Read the full Version 1 specs and sizing page.

Version 2: the larger package

Version 2 is rated for an 11 kW inverter, a 15.36 kWh nominal LiFePO4 battery and two MPPT solar inputs of 5,500 W each, enough for 14 panels of 720 W (10.08 kWp). It has a 10-year hardware warranty; exact coverage is written into your quote. The unit price is ₱150,000, unit only. It rolls on casters and weighs about 160 kg. See the Version 2 product page for every rating.

Example only: 15.36 kWh × 0.80 usable × 0.90 efficiency ≈ 11.06 kWh to your AC loads, or roughly 11 hours at a steady 1 kW. Real backup time changes with your loads, the charge left in the battery and the weather, so treat this as math, not a promise.

Both packages include:

• All-in-one unit (hybrid inverter and battery in one cabinet)
• Solar panels
• Mounting rails and roof hardware
• Electrical parts: PV cables, DC isolators and breakers, surge protection, AC breaker, grounding
• Labor: installation and commissioning

The unit price of each JH Solar version is listed above. The full system is quoted after a site assessment, because your roof, cable runs and loads change the parts list. You can compare Version 1 and Version 2 side by side, with sizing examples for each, before you get in touch.

Why Filipino Homes Look at Solar

People usually come to solar for one of three reasons: the monthly bill, brownouts, or the heat that keeps the aircon running. Each one points to a different setup.

Bills that change every month

Your rate per kWh is printed on your bill, and it changes from month to month. The Department of Energy electricity data page is a good place to follow the trend. Solar panels make power in the daytime, so the more of your use happens while the sun is up, the more of your own solar power you use directly.

Heat and aircon use

Hot afternoons are when aircon units, fans and refrigerators work hardest, and that is also when panels are producing. Panels do lose some output when they get very hot, so good airflow under the panels and honest sizing both matter.

Brownouts and backup power

If brownouts are your main worry, you need a battery. A grid-tied inverter without one shuts down during a brownout. This is called anti-islanding, and it protects the line workers fixing the grid. To keep lights, fans, the refrigerator and Wi-Fi running, you need a hybrid or all-in-one system. LiFePO4 (lithium iron phosphate) is the common chemistry for home solar batteries, and it handles deeper daily cycling than lead-acid.

Small businesses

If your shop, small office or food stall runs its main loads in the daytime, that pattern suits solar well. The questions are the same as for a home: how many kWh you use, what must keep running in a brownout, and whether the roof can carry the panels safely.

The limits of solar

Solar is not magic. It costs real money upfront, output drops on cloudy days and in the rainy season, and batteries wear with use. A good plan starts from your own numbers, and that includes any plan from JH Solar.

How Solar Computation Works in Three Steps

You do not need to be an engineer to size a system. Our free solar computation tool does the math in your browser, and the three steps below show what it is doing.

1. Daily kWh: the kWh on your bill (or bill ÷ rate per kWh) ÷ days in the billing period, or appliances’ watts × hours ÷ 1,000. Example: 800 W × 8 h ÷ 1,000 = 6.4 kWh.
2. Inverter and battery: the inverter, in kW, must cover the highest load running at the same time plus the start-up surge of motors such as aircon compressors and pumps. The battery, in kWh, is the backup energy you want ÷ (usable share × efficiency). Example: 6.4 ÷ (0.80 × 0.90) = 8.89 kWh nominal.
3. Panels: daily kWh ÷ (peak sun hours × system factor) ÷ panel size, rounded up. Example: 10 ÷ (4 × 0.75) = 3.33 kWp; 3.33 ÷ 0.72 = 4.63, so 5 panels of 720 W.

The tool’s defaults (4 peak sun hours, a 75% system factor, 80% usable battery, 90% efficiency, 620 W panels and 25% inverter headroom) are assumptions you can change. Panel strings must also pass the inverter’s voltage and current limits, which an installer checks against the datasheets.

A calculator cannot see your roof. Shade from a neighbor’s house or a mango tree, the direction the roof faces and the length of the cable run all change the final design, so the result is a starting point for a conversation, not a parts list.

Which Solar Setup Fits Your Home?

There are three common ways to set up home solar. The right one depends on whether you need backup power, whether you want to export to the grid, and how much wiring you will leave to professionals. JH Solar systems are all-in-one hybrid units, so they belong in the “Hybrid or all-in-one” column of the table below.

Off-grid

An off-grid system is not connected to the utility at all. Panels charge a battery through a charge controller, and an inverter runs your loads. Small DC-side kits for a sari-sari store light or a bahay kubo are where careful DIY makes sense, with fuses, breakers and grounding. Our off-grid solar setup guide walks through a small kit.

Hybrid

A hybrid system uses the grid and a battery together. The inverter runs your home from solar first, charges the battery, and draws from the grid when needed; in a brownout it switches essential loads to the battery. The hybrid solar system diagram shows how the backup panel is wired.

Grid-tied

A grid-tied, or on-grid, system has no battery. It cuts the daytime bill and, with net metering, can export extra power to the utility, but it shuts off during a brownout. Read the on-grid solar diagram and net metering guide.

A quick way to choose: if you mainly want a lower daytime bill and brownouts are rare where you live, a grid-tied system may be enough. If brownouts are common or you work from home, a hybrid or all-in-one system keeps your essentials running. If there is no grid line at all, go off-grid.

What Affects the Price of a Solar System

We list unit prices, not whole-system prices, because homes with the same bill can need different parts. These factors move the price of any system, from JH Solar or another provider.

For market ranges, see our guide to solar panel prices in the Philippines. Compare quotes on the same terms: kWp, usable battery kWh, inverter kW, brands and warranty. When you ask “magkano,” the answer is only clear once every line is written down.

Be careful with a quote that is far cheaper than the rest and does not explain why. Ask which brands are included, whether the battery figure is usable or nominal, and whether permits, grounding and labor are in the total.

Solar in the Philippines: Sun, Storms and Net Metering

These are the local points JH Solar looks at for every home we assess.

Peak sun hours

Peak sun hours are the day’s sunlight counted as hours of full-strength sun. In the Philippines they are typically about 3.5 to 5 a day, depending on the place and the season. Look up your city on the Global Solar Atlas and use that number in the calculator instead of our default.

Rainy season and typhoons

Output drops on overcast days, so size for an average day and decide in advance which loads you will cut when the weather turns. Mounting must suit the wind loads on your roof, with proper rails, clamps and roof attachments. Follow the PAGASA tropical cyclone signals and have the panels, rails and cables inspected after any strong storm.

Net metering basics

Net metering credits solar power you export to the utility. According to the Meralco net metering FAQ, it is for systems up to 100 kW, with an ERC Certificate of Compliance and a net-metering agreement among the papers. Cooperatives handle it for their members. Our step-by-step net metering guide for the Philippines covers the steps and fees.
