JH Solar Version 1: 7 kW, 16.38 kWh All-in-One Solar Unit

Last checked 20 October 2026 · JH Solar guide

What JH Solar Version 1 Is

JH Solar Version 1 joins three parts that are usually sold as separate boxes: a hybrid inverter that turns battery and solar DC into 230 V AC for your outlets, an MPPT solar charger, and a lithium iron phosphate battery. Because they share one cabinet, there are no external battery cables to run between boxes, and the inverter and battery are already matched.

It is plug-and-play in that sense: the hard pairing work is done inside. It is also a floor-standing unit on casters that can be moved, which makes it the step up from a hand-carry power station. The panels still go on your roof, and a licensed electrician still connects the unit to your panel board. Our Version 1 and Version 2 comparison shows how it sits next to Version 2, which has the bigger inverter and solar input.

The unit works with or without grid power. Grid power passes through it to your house panel, and when Meralco or your electric cooperative has a brownout, it switches in about 10 ms and runs the same loads from solar and the battery.

Who JH Solar Version 1 Suits

JH Solar Version 1 suits most homes on Meralco or an electric cooperative that want strong backup at night and during brownouts. With the grid connected, it fits homes using up to roughly 500 to 550 kWh a month, as the grid covers what its six panels cannot. Its big battery is the strong point. Its single solar input, which takes up to six panels, is the part that sets the ceiling.

• Grid-connected family homes: lights, fans, a refrigerator, a TV, Wi-Fi, laptops and an aircon, with the 7 kW inverter carrying them at the same time.
• Night and brownout backup: families in areas with frequent outages who want the fridge, lights and fans to keep going after dark.
• Limited roof space: homes that can fit about six large panels but not twelve or more.
• Small shops: a sari-sari store or home office that needs lights, a chiller and a laptop to survive outages.

If you need more than about 5.6 kW running at once (several aircon units together), live off-grid and use more than about 300 kWh a month, or want the most bill savings from daytime solar, the JH Solar Version 2 with its 11 kW inverter and dual MPPT inputs is usually the better match. The quickest way to see which side you are on is to run your electric bill through our solar computation tool, which shows your daily kWh and every assumption.

JH Solar Version 1 Price: ₱120,000 for the Unit

People often ask “magkano ang JH Solar Version 1?” The unit is ₱120,000. That buys the cabinet with the 7 kW inverter, the solar charger and the 16.38 kWh battery inside. It does not include the panels or the work around them.

Full Specifications

These are the rated figures for JH Solar Version 1. Keep this table handy when you read your quote.

Two numbers matter most when you plan. The 7 kW inverter rating is how much power the unit can deliver at once, and the 16.38 kWh battery is how much energy it stores. Mixing up kW and kWh is the most common sizing mistake, so read how home batteries are sized for nominal versus usable kWh.

How the Solar Input Works: One MPPT and the 3S2P Layout

JH Solar Version 1 has one solar input with one maximum power point tracker (MPPT). The tracker works between 60 V and 140 V, accepts up to 4,480 W of panel power, and must never see more than 180 V open-circuit.

Why three panels in series is the maximum

Panels in series add their voltage. Our 620 W panel is rated 48.6 V open-circuit and 41.3 V at maximum power. Three in series give about 145.8 V open-circuit and 123.9 V while working, which sits inside the MPPT window and under the 180 V limit. Four in series would reach about 194.4 V, and panel voltage climbs even higher on cool, bright mornings, so a fourth panel is never added.

Two strings in parallel

To use six panels, the installer builds two strings of three and joins them in parallel. This is called 3S2P. Parallel strings add current while keeping the voltage of one string.

The Honest Limit: Recharging 16.38 kWh From Six Panels

The battery is large, but the solar input takes only six panels, so a fully drained battery is hard to refill in one day.

Example: even if the input ran at its full 4,480 W for a 3-hour midday peak, that is 4,480 W × 3 h = 13.44 kWh, still less than 16.38 kWh. With the standard 3.72 kWp package and 20% losses, the same 3 hours give about 3.72 × 3 × 0.8 ≈ 8.9 kWh. The charging current caps out too: Example: 80 A × 51.2 V ≈ 4.1 kW into the battery at most.

Across a whole sunny day the panels give more than the peak window alone. Example: 3.72 kWp × 4 peak sun hours × 0.75 overall factor ≈ 11.2 kWh. Daytime appliances use part of that before it reaches the battery. On rainy-season days, expect less.

In practice, JH Solar Version 1 works best with the grid connected, so the grid tops up the battery between outages, or when night use leaves the battery partly charged by morning.

What JH Solar Version 1 Can Run

Two checks decide whether JH Solar Version 1 fits your loads. First, power: add up the watts of everything that runs at the same moment, plus the start-up surge of motors like a fridge compressor or aircon, and keep it under 7 kW. Second, energy: add up watts × hours for each appliance and divide by 1,000 to get kWh.

Example: the battery delivers about 16.38 kWh × 0.9 usable × 0.95 efficiency ≈ 14.00 kWh to your appliances. Only the night counts: by day the panels run the loads and refill the battery. The night without aircon uses less than a quarter of that. The night with one aircon fits with room to spare, but six panels then need most of a sunny day to refill it.

For aircon users, an inverter-type unit set at a moderate temperature is much easier on the battery than an old non-inverter one. Our guide to solar inverter limits explains motor start-up surge. In a brownout every load on your house panel runs from the unit, so what runs at once must stay under 7 kW.

Typical Wiring Summary

A Version 1 install follows a standard layout. This summary is for understanding your quote, not a do-it-yourself guide: the AC side and the panel board connection are work for a licensed electrician.

• Panels: two strings of three panels (3S2P), with mounting rated for the wind in your area.
• String fuses: each string gets its own fuse, because two strings are joined in parallel and a fault in one string could otherwise push current back through it.
• DC isolator: a switch between the panels and the unit so the solar side can be shut off for service.
• Surge protection: a DC surge protective device on the solar line, which matters in a country with frequent thunderstorms.
• AC input: the grid runs through your meter and one 2-pole breaker (40 A in the manual for this model) into the unit’s AC input. A generator, if any, also connects here. The electrician confirms the breaker and cable size under the Philippine Electrical Code.
• AC output: output 1 feeds your house panel with all its circuits (rated about 30.4 A at 230 V); output 2 is the two sockets on the unit. It draws from the grid but never exports.
• Grounding: the panel frames, rails and cabinet are bonded to a proper ground.

Electrical work in the Philippines is done by a registered master electrician or a professional electrical engineer; the Institute of Integrated Electrical Engineers of the Philippines publishes the Philippine Electrical Code they follow.

Where to Place the Unit

The battery and inverter last longer when they stay cool and dry.

• Ventilation: a shaded, dry area with airflow, out of direct afternoon sun, with open space around the cabinet as the manual specifies.
• Flood level: above the highest water your street has seen, on a raised base if needed.
• Away from LPG: keep it away from LPG tanks, the kitchen, fuel, paint and anything that burns easily.
• Short cable runs: near the panel board where possible, to limit cable length and losses.

Philippine Conditions and Tips on Your Phone

Peak sun hours in the Philippines are typically about 3.5 to 5 a day, depending on place and season. You can look up your own city on the Global Solar Atlas. During the rainy season, output can stay low for days, which is when grid top-ups and careful load choices matter most for a six-panel system.

Heat also matters: panels lose some output on hot afternoons, and batteries age faster when they run hot. Typhoon season calls for mounting that suits local wind and a check after a strong storm.

Conclusion: Is JH Solar Version 1 Right for Your Home?

JH Solar Version 1 packs a 7 kW inverter and a 16.38 kWh battery into one cabinet for ₱120,000, unit only. It gives you the bigger battery of our two units at the lower price, and with the grid connected it suits most homes using up to roughly 500 to 550 kWh a month. Its one real limit is the solar side: the 180 V input allows at most six panels in a 3S2P layout, so it cannot refill a fully drained battery in one short peak.

Start with your bill, check your night loads against the examples above, and send us the details for a site assessment. You can also read more about JH Solar and our other guides on the homepage.
