Sunsynk Inverter Review (Philippines): ECCO Hybrids With a Certified Local Distributor
Published specifications for the ECCO hybrid range. A brand ships several series, so these figures describe this model and not every product the manufacturer sells.
- Rated power
- 3.6-7 kW single phaseThree phase runs 8 kW to 50 kW. Parallel up to 16 units, so a system can grow past one inverter.
- Type
- Hybrid, dual MPPT
- Maximum efficiency
- not publishedNot stated in the sources we checked.
- MPP trackers
- 2The 3.6 kW ECCO is rated 3,600 W output with a maximum 7,000 W DC input across its two trackers.
- Warranty
- 5 years, 10 with a Sunsynk batteryThe battery has to be added within three months. Miss that window and you stay on five years.
- Philippine channel
- EcoSolutions, authorised distributorThe same company that distributes AIKO panels, so a panel and an inverter can come through one channel.

What it does well
- An authorised Philippine distributor in EcoSolutions, which also carries AIKO, so a full system can come from one accountable party.
- Parallels up to 16 units, so the system can grow well beyond a single inverter without replacing what is already fitted.
- The warranty doubles to 10 years if you add a Sunsynk battery within three months, so it is worth planning the battery in at purchase.
Where it falls short
- The 10-year warranty is conditional on adding a Sunsynk battery within three months, which is an easy deadline to miss.
- No maximum efficiency published in the sources we checked, so it cannot be compared against Sungrow or Huawei on the figure that compounds over the system life.
- A single authorised distributor is a single point of failure in the support chain.
Compare against the other 29 hybrid inverters we have reviewed
How the ECCO hybrid range compares with the other hybrid inverters we have reviewed. Listed in no particular order — this puts published figures side by side, it does not pick a winner. Scroll the table sideways to see every column.
Dashes are figures the manufacturer does not publish, not zeros. Where two products differ on a spec, which one matters depends on your roof and your usage — a higher efficiency panel earns its premium on a small roof and rarely on a large one.
Sunsynk is one of the more established hybrid inverter brands globally — over two decades in the market, selling into more than 40 countries, and one of the most popular hybrid choices in the UK.
It matters here because EcoSolutions is its authorised Philippine distributor, the same company that distributes AIKO panels. EcoSolutions builds systems around that pairing, which means Sunsynk arrives with a named local channel rather than as a marketplace import.
The ECCO range
ECCO is the hybrid line most relevant to homes:
- Single-phase models including 3.6kW and 7kW
- Three-phase from 8kW up to 50kW
- Parallel up to 16 units, so a system can grow well past a single inverter
- Dual MPPT inputs — useful on the multi-plane roofs common here, letting two arrays at different orientations run independently
- Weatherproof construction
- Built-in generator input, which matters more in the Philippines than in most markets given how many homes already run a genset
- Programmable time-of-use scheduling
As a worked example, the 3.6kW ECCO is rated at 3,600 W with maximum DC input of 7,000 W across its dual MPPTs.
The generator input deserves a note. If you currently run a generator through brownouts, a hybrid inverter that accepts genset input lets the two coexist rather than forcing an either/or.
Warranty
5 years standard, extending to 10 if you add a Sunsynk battery — but the extension must be done within 3 months of the original installation.
That condition is the thing to catch. If you are buying the inverter now and planning storage “later”, later needs to mean within three months or you keep the 5-year term. Decide that before you sign, not after. Our retrofitting a battery guide covers the wider version of this problem.
Five years standard is mid-pack — Growatt is also 5 extendable to 10, and Solis offers similar. It is shorter than what Sungrow publishes as standard.
Local availability
EcoSolutions, certified distributor. The company also handles installation and solar panel cleaning, and specifies Sunsynk inverters with AIKO panels in its own builds.
That is a genuine channel, with the usual caveat for a brand at this stage: the Philippine installed base is smaller than Deye or Growatt, which most local crews have wired many times over. Ask your installer whether they have commissioned a Sunsynk before, and confirm the warranty registration process.
What it costs in the Philippines
We have no verified Philippine pricing specific to Sunsynk. It sits in the mid-range of our hybrid inverter price guide:
| Inverter size | Budget-mid tier | Premium tier |
|---|---|---|
| 5 kW | ₱25,000-70,000 | ₱75,000-120,000 |
| 6 kW | ₱30,000-80,000 | ₱90,000-130,000 |
| 8-10 kW | ₱55,000-95,000 | ₱110,000-150,000 |
Get an itemised quote from EcoSolutions or your installer and compare against that band. Remember the battery is the larger cost — ₱13,000-23,000 per usable kWh installed, per the battery price guide — and that adding one within three months is what protects the longer warranty.
Where it falls short
- Smaller Philippine installed base than the dominant Chinese hybrids.
- The 3-month battery window on the warranty extension is easy to miss.
- Single distributor channel, which is accountable but not price-competitive.
- 5-year standard warranty is respectable rather than leading.
Who it’s best for
Homes wanting a well-featured hybrid with a named Philippine distributor, particularly if dual MPPT suits your roof, you already run a generator, or you expect to expand the system later using the parallel capability.
If you want the brand your installer has fitted a hundred times, Deye or Growatt remain the safest defaults. Compare the field in the best solar inverter roundup.
