Battery Storage Products by Brand

Every battery storage brand uses its own product line names and offers multiple capacity configurations, making it easy for consultants to get lost in a forest of model codes. This document maps the LiFePO₄ battery brands commonly found in Vietnam along two axes: batteries synchronized with a specific inverter brand versus open batteries compatible with multiple brands, and low-voltage versus high-voltage batteries. How to read individual spec-sheet parameters is covered in 03-02, so this chapter does not repeat that. It focuses on correctly identifying each product line and placing it in the right cell of the map.

For: sales staff who need a product-line map for quick consultation, technicians matching batteries to inverters by exact line name, and newcomers who need to know which brand offers which battery line.

Quick summary

Battery storage products split along two axes. The first axis is synchronized versus open. Synchronized batteries are made by the inverter brand itself; the inverter–battery pair has already been tested and validated, BMS communication is standardised, and warranty is centralized, but you are locked into one ecosystem. Open batteries are made by dedicated battery specialists and are compatible with multiple inverter brands as long as the compatibility list matches; they offer flexibility and cost optimization but require correct protocol configuration.

The second axis is low-voltage versus high-voltage, as distinguished in 01-05. Low-voltage batteries operate around 48 to 51.2 V, one pack of 16 cells, suitable for single-phase residential systems, and scale by connecting multiple packs in parallel. High-voltage batteries stack multiple modules in series to reach hundreds of volts, suitable for three-phase and higher-power systems, and scale by adding modules to a tower and then connecting multiple towers in parallel.

A product falls at the intersection of the two axes. For example, the Sungrow SBR is a synchronized high-voltage battery, while the Pylontech US5000 is an open low-voltage battery. Correctly identifying where a battery line sits on the map is the first step toward giving accurate advice.

Synchronized batteries by inverter brand

Synchronized batteries are batteries designed and sold by the inverter brand as part of their system. The advantage is that the inverter–battery pair has already been tested and validated by the manufacturer, BMS communication is standardized, and warranty is centralized. Most major brands are now pushing high-voltage stacked lines for residential and small commercial use; a few brands maintain a parallel low-voltage line for single-phase systems.

The Sungrow SBR is a high-voltage stacked battery for residential and small commercial systems, using 3.2 kWh modules at 64 V. One tower connects 3 to 8 modules to deliver approximately 9.6 to 25.6 kWh, and up to 4 towers can be connected in parallel for approximately 102 kWh usable. The datasheet specifies IP55 and CAN communication, with a 10-year warranty. This is the SBR line for three-phase residential segments, distinct from the SBH line below, which targets larger capacities.

The Sungrow SBH is a higher-power high-voltage line using 5 kWh modules at a nominal ~70.4 V (~71 Ah) with a higher continuous current rating than the SBR. One tower connects 4 to 8 modules for 20 to 40 kWh, and up to 4 towers in parallel for 160 kWh. The nominal voltage of an 8-module tower is around 563 V, firmly in the high-voltage range for three-phase and commercial systems.

The Huawei LUNA2000 spans two generations and must be called by the correct name. The older S0 uses 5 kWh modules in 1 to 3 module configurations for 5, 10, or 15 kWh, with a nominal voltage around 450 V. The newer S1 uses 6.9 kWh modules for 6.9, 13.8, or 20.7 kWh per tower, supporting both single-phase and three-phase with different voltage ranges (approximately 350 to 560 V for single-phase and 600 to 980 V for three-phase), rated IP66 with a 10-year warranty. Both are high-voltage batteries synchronized with the SUN2000 inverter.

GoodWe offers both voltage families. The Lynx Home F is a high-voltage battery using 3.27 kWh modules at 102.4 V, stacked 2 to 5 modules for approximately 6.55 to 16.38 kWh with a nominal voltage from 204.8 V to 512 V. The Lynx Home U is a low-voltage 51.2 V battery that scales by connecting multiple units in parallel for 5.4 to 32.4 kWh, suited for single-phase systems. When consulting, always confirm whether the inverter is a high-voltage or low-voltage type to select the correct family.

The SolaX Triple Power T-BAT HV 5.8 is a high-voltage battery using units of 5.8 kWh at a nominal 115.2 V, consisting of one Master unit and Slave units connected in series. The V3 version connects 1 to 6 units for 5.8 to 34.6 kWh per string, with usable capacity of approximately 5.5 kWh per unit at 95% depth of discharge (DoD), expandable to 12 units (~69.1 kWh) with inverters that have two battery ports. The V3 datasheet specifies IP66, more than 6,000 cycles, and a 10-year warranty. Note that the older V2 is limited to fewer units (around 3 to 4 units, ~23 kWh) and its published DoD differs, so always cross-reference the datasheet for the version currently on sale.

Sofar offers the high-voltage GTX line and the BTS module line for HYD-series hybrid inverters. The GTX 3000-H uses 2.56 kWh stacked modules; a GTX 3000-H4 to H10 system connects 4 to 10 modules for approximately 10 to 25 kWh total and 9 to 23 kWh usable, retaining 90% of rated capacity. Nominal voltage increases with the number of modules, from approximately 204.8 V at H4 to 512 V at H10, charge/discharge current 30 A, rated IP65 and over 6,000 cycles. This is a high-voltage line, entirely distinct from the low-voltage 51.2 V single-unit products such as the SF-16KWH-L1 analyzed in 03-02.

Deye offers both voltage families within the SUN inverter ecosystem. The SE-G5.1 Pro is a low-voltage 51.2 V, 100 Ah unit at 5.12 kWh, scalable to a maximum of 64 units in parallel for approximately 327 kWh, rated IP20 for indoor installation only, with a 10-year warranty and up to 1C charge/discharge rate. Alongside this, Deye offers the BOS-G high-voltage stacked line for large three-phase systems, using 5.12 kWh modules stacked 3 to 12 per tower for approximately 15.36 to 61.44 kWh total and approximately 13.82 to 55.29 kWh usable, nominal voltage 153.6 to 614.4 V, rated charge/discharge current 100 A with a 125 A peak, rated IP20, with CAN and RS485 communication.

Open batteries compatible with multiple brands

Open batteries are manufactured by dedicated battery specialists and are not tied to a single inverter brand; instead they publish a compatibility list of supported inverters via CAN or RS485 protocols. The advantage is the ability to select inverter and battery independently for price and application, with easy scalability. The trade-off is that protocol configuration must be done correctly and warranty is handled through multiple parties.

The BYD Battery-Box Premium splits into two lines, both high-voltage. The HVS uses 2.56 kWh modules at 102.4 V; one tower connects 2 to 5 modules for 5.1 to 12.8 kWh at a nominal voltage of 204 to 512 V. The HVM uses 2.76 kWh modules at 51.2 V; one tower connects 3 to 8 modules for 8.3 to 22.1 kWh. Both can connect up to 3 towers in parallel, reaching 38.4 kWh for the HVS and 66.2 kWh for the HVM. BYD is well known for broad compatibility with many inverter brands.

Pylontech is the most familiar low-voltage name in Vietnam. The US5000 is a 48 V low-voltage module rated at 4.8 kWh nominal and 4.56 kWh usable, with 95% DoD, rated IP20, scalable to a maximum of 16 units in parallel for 76.8 kWh, CAN and RS485 communication, over 6,000 cycle life, and a 10-year warranty. Alongside the low-voltage line, Pylontech offers the Force H2 high-voltage battery using 3.55 kWh modules at 96 V; one tower connects 2 to 4 modules for 7.1 to 14.2 kWh at a tower voltage up to 384 V. This is a clear illustration of a single brand offering both LV and HV. The two families must never be mixed.

Dyness offers the Tower high-voltage line and the PowerBox low-voltage line. The Tower uses high-voltage stacked modules; for example, the Tower T7 delivers approximately 7.1 kWh usable at a nominal 192 V, scalable in steps to approximately 21.3 kWh per tower with a system voltage range of approximately 192 to 576 V, a 10-year warranty, and a recommended DoD of 95%. The PowerBox line (for example the Powerbox F-2.5) is a low-voltage 48 V product using 2.4 kWh modules connected 1 to 4 per group, up to 5 groups in parallel for approximately 48 kWh, voltage range 42 to 54 V, rated IP65, over 6,000 cycles, and a 10-year warranty.

The WECO 5K3, current version 5K3 XP, is a dual-mode voltage module using a 5.37 kWh unit. In low-voltage mode at 51.2 V (range 46.5 to 58.4 V), up to 15 units can be connected in parallel for approximately 80.55 kWh with a charge/discharge current up to 100 A. In high-voltage mode, up to 16 units can be connected in series for approximately 86 kWh, system voltage 150 to 1,000 V with a lower current of approximately 25 A. The 5K3 XP datasheet specifies IP65, over 6,000 cycles at 90% DoD, a 10-year warranty, and full CAN, RS485, and RS232 communication. WECO is the choice for some project systems requiring a wide scalability range.

The Seplos Mason is a popular DIY low-voltage 51.2 V battery kit in the self-build community. The Mason 280 is assembled from 16 cells of 280 Ah for approximately 14.3 kWh per unit, with a 16S 200 A BMS, expandable to a maximum of 32 units in parallel, rated IP20. This is not an off-the-shelf packaged battery from a major manufacturer: it is a frame and BMS for the user to assemble their own cells. It therefore suits technically knowledgeable users rather than general customers, and safety certification must be carefully evaluated per 03-05.
