GoodWe Inverter Review (Philippines): Reliable, Well-Distributed, Slightly Pricier
Published specifications for the ES G2 (GW5000-ES-20). A brand ships several series, so these figures describe this model and not every product the manufacturer sells.
- Rated power
- 5 kW single phaseES G2 spans 3–6 kW. EM tops out near 2.3 kW; ET serves three-phase.
- Type
- Hybrid, low-voltage battery
- Maximum efficiency
- not publishedNot published for the ES G2 in the sources checked. GoodWe's three-phase ET Plus+ reaches about 98.1–98.2%; do not assume the same here.
- MPP trackers
- 2PV input to 7,500 W, 16 A per tracker.
- Backup switchover
- Under 10 ms
- Warranty
- 5 years
- Ingress protection
- not publishedNot stated for the ES G2. The ET G2 series is IP66; do not assume the same.

What it does well
- Backup switchover under 10 ms, fast enough that a desktop computer or a router rides through the transfer.
- Fanless construction, so there is no fan to fail and nothing audible in a utility room.
- A named Philippine distributor, Solaric, so there is a local party behind a claim.
Where it falls short
- A 5-year standard warranty, half Sungrow's 10 years on a comparable hybrid.
- Neither maximum efficiency nor an ingress rating is published for this model, so it cannot be compared on either.
- The ES, EM and ET series differ substantially in capability — confirm which one you are being quoted rather than comparing on the brand.
Compare against the other 29 hybrid inverters we have reviewed
How the ES G2 (GW5000-ES-20) 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.
GoodWe sits a notch above Deye and Growatt on perceived build quality and local distribution clarity, at a modest price premium. If you want a hybrid inverter backed by one of the Philippines’ more established solar retailers rather than a patchwork of importers, it’s one of the stronger picks in this tier.
Local availability
Solaric, one of the longer-running solar retailers in the Philippines, carries GoodWe grid-tie and hybrid inverters directly, which gives buyers a single accountable local seller rather than a scattered reseller network. That matters for warranty service and spare-parts availability — two things that are harder to chase down once a fragmented importer network is your only option.
Efficiency, specs, and warranty
GoodWe’s lineup splits into a few series worth knowing apart: ES (single-phase, on-grid and off-grid capable, up to 4.6kW charge/discharge), EM (single-phase, also backup-capable but with a lower ~2.3kW/2.3kVA ceiling, the more budget line), and ET (three-phase, larger residential and small-commercial systems, with the ET Plus+ series reaching around 98.1-98.2% peak efficiency). Standard warranty across the hybrid lineup is 5 years. GoodWe has also run a recurring free warranty-extension program pushing eligible hybrid inverters and batteries to 10 years when paired with a qualifying GoodWe battery (Lynx or BAT series) and registered through their PLUS+ program — a genuinely useful perk if your installer sets up a matched GoodWe battery alongside the inverter, though confirm the current terms apply to your specific model and purchase channel, since GoodWe has revised this promotion across several regional versions.
Price
Solaric’s listed grid-tie inverter pricing runs roughly ₱44,500-₱81,500 depending on capacity, and hybrid ES/EM/ET units generally price at or above that band once storage-ready features are added — expect a modest premium over Deye or Growatt for comparable capacity.

Where it falls short
The main trade-off is price — GoodWe isn’t the cheapest hybrid option in the Philippine market, and buyers chasing the lowest ₱/kW figure will usually land on Deye or Growatt instead. The EM series’ lower backup ceiling (~2.3kW/2.3kVA) also means it’s a poor fit if you’re planning to lean heavily on battery backup during outages; the ES or ET series suit that use case better. As with any hybrid inverter, the free warranty extension is conditional on using GoodWe’s own battery ecosystem, so it’s less useful if you’re mixing in a third-party battery brand.
Who it’s best for
Buyers who’d rather pay a little more for a single accountable local distributor and an inverter-plus-battery ecosystem with a real extended-warranty program, especially if reliability and after-sales support matter more to you than shaving the last few thousand pesos off the quote.
