Hybrid Inverter Products by Brand

After building the model-name map in 04-08, the next step in any consultation is knowing which hybrid inverter lines each brand offers, what power ratings they cover, whether they use low-voltage or high-voltage batteries, and how efficient they are. This document describes the most common residential hybrid inverter lines available in Vietnam, brand by brand, with specifications cross-referenced against official datasheets, so you can select the right inverter for each single-phase or three-phase application.

For: sales staff comparing products by brand, technicians looking up string design parameters, newcomers who need a market-level product overview.

Quick summary

The market divides into two broad groups by battery type. The high-voltage battery group includes Sungrow SH series, Huawei SUN2000 L1, GoodWe EH, SolaX Hybrid G4, Sofar HYD, and Fox ESS H3 Smart; these deliver lower charge/discharge currents, neater cabling, and slightly higher efficiency. The low-voltage 48V group is represented by Deye SUN-SG04LP, Solis S6 L variant, and GoodWe ET LV; they make it easy to mix batteries from multiple brands and are popular in open systems. Some brands offer both low-voltage and high-voltage variants within the same product family, for example Solis S6 three-phase and GoodWe ET.

By market segment, Sungrow and Huawei lead the premium synchronized tier with three-phase efficiency up to 98.4%. Deye is very widely used in Vietnam because of competitive pricing, flexible 48V batteries, and the ability to deliver roughly 1.5× rated power for short periods to start heavy loads. GoodWe, SolaX, Sofar, and Solis occupy the mid-to-upper-mid range with full single-phase and three-phase coverage. Sigenergy takes an all-in-one approach, integrating the inverter and battery into a single enclosure.

Typical single-phase ratings are 3 to around 10 kW for residential use; three-phase ratings run from 5 kW up to 20–25 kW for larger loads. For ecosystem comparisons (closed vs. open systems) see 04-08; this document focuses on product specifications.

Sungrow

Sungrow is one of the most popular premium synchronized brands, using high-voltage SBR and SBH batteries managed through the iSolarCloud app. The single-phase SH-RS line covers residential homes, the three-phase SH-RT line suits villas, and the SH-T series scales up to small commercial. Key strengths are high efficiency and fast backup switching; the three-phase variant supports 100% unbalanced phase loading.

The commercial SH5T–SH25T series extends to 5–25 kW three-phase with up to 3 MPPT inputs on higher-power variants, still using SBH and SBR batteries through iSolarCloud.

Huawei

Huawei follows a closed ecosystem approach with the SUN2000 inverter, high-voltage LUNA2000 battery, and FusionSolar app. The residential single-phase line is the SUN2000 L1; the three-phase lines are the M1 and MB variants. Distinguishing features are very high efficiency and battery-stack-level optimization; only LUNA2000 batteries are supported, making this a tightly integrated system.

The three-phase M1 and MB variants raise the power range to 8–20 kW and above, still paired with LUNA2000. Consult the correct model-specific datasheet, as Huawei releases many market variants.

GoodWe

GoodWe has two residential hybrid families. The single-phase EH family uses the high-voltage stacked Lynx Home battery; the three-phase ET family is available in both a low-voltage 48V variant (ET LV) and a high-voltage variant. Monitoring is through the SEMS Portal. Key strengths are UPS-class backup switching speed and fanless natural-convection cooling on the EH line.

The Lynx Home F battery uses stackable LFP modules of approximately 3.27 kWh each. A minimum of two modules is required to reach the voltage threshold for the EH, ET, BH, and BT inverters.

SolaX

SolaX uses high-voltage Triple Power batteries with the SolaX Cloud app; the G4 generation is the current mainstream line. The X1-Hybrid G4 is the single-phase residential unit; the X3-Hybrid G4 is the three-phase unit for larger loads, supporting parallel stacking and both grid-tied and off-grid operation.

SolaX allows PV array oversizing up to 200% on G4 models, but the per-MPPT input current limit must still be respected when designing strings.

Sofar

Sofar uses the HYD line for both single-phase and three-phase applications, supporting lithium or lead-acid batteries, monitored through SOFAR Cloud and Solarman. The three-phase HYD 5-20KTL-3PH is popular for larger households and small commercial sites, with support for up to two battery inputs on higher-power variants.

Sofar also offers smaller single-phase HYD models; confirm the correct single-phase model name when specifying for a residential customer.

Solis

Solis uses the S6 Hybrid line with the SolisCloud app. A notable feature is that Solis offers both an L (low-voltage 48V) variant and an H (high-voltage) variant, making it suitable for both synchronized and open systems. The 200% overload capability for 10 seconds in off-grid mode makes it well suited to starting pumps and air conditioners.

Solis also offers H (high-voltage) variants for both single-phase and three-phase, compatible with high-voltage batteries such as BYD HVL in some markets. Always confirm whether you need the L or H variant before pairing batteries.

Deye

Deye is very popular in Vietnam for its competitive pricing and flexible 48V low-voltage batteries, which make it easy to pair with batteries from multiple brands in open systems. Model names follow the pattern SUN-xK-SG04LP1 for single-phase and SUN-xK-SG04LP3 for three-phase, monitored through Deye Cloud. A notable characteristic is peak power output of approximately 1.5× rated power for short durations to start heavy loads.

Additional brands

Several other brands are present in Vietnam. Sigenergy takes an all-in-one approach with SigenStor, combining the inverter, stacked battery modules, and energy management in a single enclosure; single-phase variants run approximately 3–12 kW and three-phase 5–25 kW, monitored through the mySigen app. AUXSOL uses the ASG inverter line with ABL batteries and the AUXSOL Cloud app, covering approximately 3.6–10 kW single-phase and 5–20 kW three-phase, 2 MPPT inputs, MPPT range approximately 170–900 V, maximum efficiency approximately 97.7%, and backup transfer under 10 ms. Fox ESS offers the H3 Smart three-phase line at 5–15 kW with up to 3 MPPT inputs, MPPT range approximately 120–950 V, high-voltage battery support approximately 100–800 V, and monitoring through FoxCloud.
