Solis, Deye, and Growatt are the three most-installed hybrid inverter brands in the Philippines as of 2026.
Why Solis, Deye, and Growatt Dominate the Philippine Market
Walk into any solar installation in the Philippines today and the inverter is almost certainly a Solis, Deye, or Growatt. These three brands have captured the mid-range Philippine market because they hit the sweet spot: technically solid, competitively priced, and -- critically -- they have enough Philippine market presence that distributors, spare parts, and warranty support are actually reachable.
That last point matters more than most comparisons acknowledge. A premium European brand might outperform all three on paper, but if a fault develops and the local distributor has no parts in-country, you are waiting months. The three brands in this comparison have established enough Philippine footprint to make real-world warranty support feasible.
In this guide we go beyond the basic Solis vs Deye question and include Growatt -- the fastest-growing budget-tier brand in the Philippine market -- so you can make an informed three-way comparison based on your specific situation.

Solis vs Deye vs Growatt: Full Spec Comparison (6KW Hybrid)
The table below covers the specifications that matter most for Philippine residential and commercial hybrid installations. We focus on 6KW hybrid models as the most popular configuration.
Solis -- Deep Dive for the Philippine Market
Solis is manufactured by Ginlong Technologies, a publicly listed company (Shanghai Stock Exchange) founded in 2005. With over 300GW of inverters deployed globally, Solis is not a small player. In the Philippines, Solis has been present since around 2016 -- giving it the longest on-the-ground track record of the three brands in this comparison.
Solis Strengths
- Longest Philippine track record -- more installers across Cebu, Davao, Metro Manila, CDO, and Iloilo are deeply familiar with Solis configuration and troubleshooting
- Solis Cloud monitoring is the most mature and reliable platform of the three -- real-time data, historical yield tracking, and alert notifications are all well-implemented
- 300GW+ global deployments mean Solis firmware is battle-tested across varied climate conditions
- Better resale value -- Solis is the most recognized inverter brand name when selling a property with solar installed
- EPS switchover under 20ms -- fast enough that most appliances including desktop computers do not notice a brownout transition
Solis Weaknesses
- Highest price of the three -- typically 15-25% more expensive than Growatt for comparable specs
- Some newer Solis S6 series models have firmware compatibility issues with certain LiFePO4 BMS protocols -- confirm the specific firmware version with your installer before purchasing
- Innovation pace is slower than Deye -- EV charging integration and advanced off-grid features arrived later in the Solis lineup
Deye -- Deep Dive for the Philippine Market
Deye is a newer brand (est. 2013) but has grown rapidly. Their hybrid inverter lineup -- particularly the SUN-xK-SG04LP3 series -- has become one of the most installed models in the Philippines for off-grid and hybrid residential use. Deye's aggressive feature development and competitive pricing have made them the brand to watch.
Deye Strengths
- 10-15% lower price vs Solis -- on a full P330,000-P450,000 system, the inverter price difference is P5,000-P8,000
- Best off-grid and parallel operation features -- Deye is the go-to for community solar microgrids, farm systems, and island off-grid applications where parallel inverter stacking is needed
- EV charging integration on newer models -- forward-compatible as EV adoption grows in the Philippines
- Fastest feature development pipeline -- firmware updates add capabilities regularly; Deye users consistently get new features before Solis or Growatt equivalents
Deye Weaknesses
- Shorter Philippine track record -- fewer years of local field data compared to Solis
- Early Deye models (pre-2023) had communication board failures in some units -- always check the manufacture date and confirm current firmware is installed before commissioning
- Philippine after-sales network is growing but still smaller than Solis -- more critical in provincial areas where installer density is lower
Growatt -- Deep Dive for the Philippine Market
Growatt is the least-discussed of the three in the Philippines but globally is actually the largest of the group by unit volume -- with over 7 million inverters installed across 130 countries. In the Philippines, Growatt entered the market around 2018 and has positioned itself as the budget-friendly option without sacrificing core functionality.
Growatt Strengths
- Lowest price of the three -- a Growatt 6KW hybrid is typically P5,000-P15,000 cheaper than the equivalent Deye, and P10,000-P20,000 cheaper than Solis
- Massive global installed base -- 7M+ units means firmware issues are identified and patched quickly; you benefit from global scale
- Good LiFePO4 battery compatibility -- Growatt inverters pair well with major battery brands via CAN or RS485 BMS communication
- Straightforward configuration -- the ShinePhone app and Growatt setup wizard are simple for installers to use
Growatt Weaknesses
- Smallest Philippine support network -- authorized Growatt distributors in the Philippines are fewer than Solis and Deye; provincial areas may have limited warranty support access
- ShinePhone app reliability -- reported to disconnect more frequently than Solis Cloud or SolarmanBusiness, particularly on 5GHz router configurations; use 2.4GHz WiFi for the monitoring module
- EPS switchover time (~30ms) is slightly slower than Solis and Deye -- not significant for most household loads
- Fewer off-grid and parallel stacking features compared to Deye -- not ideal for community or commercial three-phase applications

Put the price in context: On a complete P330,000--P450,000 hybrid solar system, the inverter is roughly 7-10% of total cost. Saving P10,000 by choosing Growatt over Solis is a 2-3% system cost reduction. Choose based on support quality and your use case -- not purely on unit price.
Which Inverter for Your Situation?
There is no universally best brand. The right choice depends on your load profile, location, budget, and whether you are going on-grid, hybrid, or off-grid.
| Your Situation | Recommended | Why |
|---|---|---|
| Standard 3-6KW home, VECO/MERALCO net metering | Solis | Best PH track record, reliable Solis Cloud monitoring, strong installer familiarity |
| Budget residential, non-critical loads, tight budget | Growatt | Lowest unit price, solid core functionality, good global support base |
| Off-grid farm, island property, sitio installation | Deye | Best parallel stacking and off-grid features; excellent without grid connection |
| Commercial 3-phase building or warehouse | Deye or Solis | Both have 3-phase options; Deye slightly more competitive on price |
| Community barangay microgrid | Deye | Parallel inverter stacking is Deye's strongest feature |
| EV charging integration (future-proofing) | Deye | EV-ready models in current Deye lineup; Solis and Growatt less mature on EV |
| Best resale value / selling property with solar | Solis | Most recognized inverter brand in Philippine real estate market |
Common Issues -- and How to Avoid Them
These are the most frequently encountered issues SolarStream sees in the field with each brand. Knowing them upfront lets you avoid them at commissioning.
BMS Protocol Mismatch
Some Solis S6 series units have firmware that does not fully support older CAN BMS protocols used in some LiFePO4 batteries. Always confirm your battery BMS protocol (CAN 2.0 vs RS485) matches the inverter firmware version before installation.
Communication Board Failures (Pre-2023 Units)
Early Deye units manufactured before mid-2023 had a higher-than-average communication board failure rate. When purchasing Deye, ask the installer to confirm the manufacture date and that current firmware is pre-installed and tested before mounting.
ShinePhone WiFi Disconnections
The Growatt monitoring module (Shine WiFi) has known connectivity issues on 5GHz-only routers. Configure your home router to broadcast a 2.4GHz network and use that SSID for the monitoring module. This resolves 90% of disconnection reports.
The most important factor across all three brands: Local after-sales support from your installer. An inverter with a 10-year warranty from a brand with no Philippine service presence is practically unclaimable. Always ask: "Can you process a warranty claim for this brand locally, without shipping the unit overseas?"
SolarStream's Honest Recommendation
For most residential installations: Solis or Deye -- both are excellent
SolarStream installs all three brands depending on system requirements, client budget, and stock availability. For straightforward residential hybrid systems (3-10KW) with VECO or MERALCO net metering, Solis and Deye perform within acceptable tolerance of each other. We lean toward Solis for clients who prioritize maximum peace of mind and the longest Philippine track record. We lean toward Deye for commercial, off-grid, and community applications where its parallel operation and EV capabilities are genuinely useful.
We recommend Growatt for clients where budget is the primary constraint and the installation is a straightforward residential hybrid on a stable grid connection. Growatt's Philippine support network is the thinnest of the three, but for uncomplicated systems in urban areas with good installer support, it delivers strong value.
The bottom line: the brand matters less than who installs it, configures it correctly, and can service it when something goes wrong three years from now.
