Solis Inverter Review (Philippines): The Volume Leader Playing Value
Solis is the inverter brand of Ginlong Technologies, and by shipment volume it’s one of the biggest names in the business — it holds the global #1 spot in residential single-phase string inverter shipments and ranks as the world’s third-largest inverter manufacturer overall. That scale is what lets Solis sit in the mid-tier price band while still offering hardware that performs close to premium brands like Huawei or SMA. It’s a sensible string or hybrid pick for homeowners who want proven volume and a real local support channel without paying a premium-brand markup.
Local availability
Solaric, one of the longest-running installers in the Philippines, is a confirmed authorized distributor of Solis and carries a wide range — from small single-phase units (the Solis-mini and Solis-1P lines) up through three-phase commercial inverters. Solis has reportedly been present in the Philippine market since around 2016, which is long enough that a fair number of local installers are already familiar with configuring and troubleshooting it, and that matters more than a spec sheet once your system is actually running. That said, Solaric appears to be the clearest named distributor we could verify — if you’re buying through a smaller reseller or an online marketplace listing, confirm you’re getting an authorized unit with local warranty backing rather than a grey-market import.
Efficiency, lineup & warranty
Solis’s current residential lineup runs on its S6 platform: S6 series grid-tie string inverters, and S6-EH1P hybrid units spanning roughly 3.8kW to 11.4kW for single-phase homes, with larger three-phase hybrid and string options above that. Efficiency figures are genuinely strong — Solis’s larger three-phase string inverters post peak efficiencies up to 98.8% with CEC-weighted efficiency around 98.3%, and smaller residential units still land in the high-97% range. The hybrid units are UL 9540-certified for battery pairing and support HV lithium batteries from several major brands (BYD, Pylontech, LG among them) — but pairing with a battery not on Solis’s published compatibility list voids the inverter warranty, so that list is worth checking before you commit to a battery brand.
Warranty terms vary more than we’d like by market and model: Solis commonly ships with a 5-year standard warranty in some regions (extendable to 10, 15, or up to 20 years as a paid add-on you register within 12 months of install), while some residential hybrid models in other markets list a 10-year standard term out of the box. Confirm the exact standard warranty year count and extension pricing for the specific model and market your installer is quoting — don’t assume it matches what you’ve read about a US or European listing.
Value for money
This is Solis’s strongest case. Rough Philippine pricing for the inverter unit alone runs about ₱25,000–₱35,000 for a 5kW hybrid, ₱30,000–₱42,000 for 6kW, and ₱55,000–₱75,000 for 10kW — figures pulled from retailer and installer listings, so treat them as ballpark and always get an itemized quote. At that price point you’re getting efficiency and monitoring (Solis Cloud) that compare well against premium brands costing noticeably more, which is exactly the value-tier positioning Solis is going for.
Where it falls short
Within the Philippine value-inverter segment, Solis is generally the more affordable option against Deye at comparable capacity, which also has a growing local footprint and stronger off-grid feature sets on some models — so if off-grid performance matters more to you than price, Deye is worth a closer look even though it typically costs more. We also found at least one source describing firmware update complications on newer models; we don’t have enough independent, verified complaint volume to call this a pattern rather than an isolated report, but it’s worth asking your installer about firmware stability on the specific model you’re quoted. The standard warranty length also varies confusingly by model and market, so get it in writing rather than assuming.
Who it’s best for
Solis suits homeowners who want a high-volume, well-proven brand with a verifiable Philippine distribution channel and strong efficiency numbers, without paying premium-brand pricing. If off-grid performance is your top priority, it’s worth cross-shopping against Deye before you decide — see our other reviews for how the mid-tier field compares.
