For comparison, the BYD HVS/HVM also specifies the same threshold (6,000 cycles), placing the G2 in the upper tier of the HV segment for prosumers. - **2.56 kWh modular architecture** - The system is built from independent 2.56 kWh modules, which allows for gradual expansion of capacity from 7.68 to 20.48 kWh per tower without replacing existing components. By using a combiner box, it is possible to connect 4 towers and achieve a total capacity of up to 81.92 kWh - a level of flexibility not available in single-unit solutions offered by competitors (e.g., Pylontech Force H2). - **Roundtrip efficiency ≥95% and IP65 rating** - The charging and discharging cycle efficiency of ≥95% is at the level of leading HV segment products (e.g., SENEC Home V3: approximately 94%). The IP65 rating allows for outdoor installation without the need for additional protective enclosures, which reduces costs and simplifies assembly. - **Robust support from AISWEI's manufacturer** - Solplanet is a brand of AISWEI - the former Chinese subsidiary of SMA (established in 2007), which ranked 6th in the global ranking of PV inverter manufacturers according to S&P Global Commodity Insights in 2023, with annual production capacity exceeding 3 GW. This is a significant argument in favor of its financial stability and ongoing service availability. - **BMS with cell-level monitoring** - The battery management system monitors each individual cell (not just the pack) independently, which allows for the early detection of thermal anomalies and extends the lifespan of the pack. This solution is comparable to the BMS used by AlphaESS Smile T10, and is less common in products from the tier-2 segment. ### Cons - **The Solplanet inverters create a closed ecosystem.** - Ai-HB G2 is certified exclusively for use with Solplanet hybrid inverters (T2/T3 series). Integration with inverters from other manufacturers (SMA, Fronius, Huawei) is only possible via Modbus, with limited functionality - unlike the BYD HVS/HVM, which are natively compatible with >20 inverter brands. - **The G2 series is being superseded by the G2 Pro.** - Meanwhile, Solplanet's offering includes the Ai-HB G2 Pro series, which boasts a declared lifespan of 8,000 cycles (approximately 33% more than the standard G2's 6,000), while maintaining a similar modular architecture. For clients evaluating the total cost of ownership (TCO) of the G2 Pro, it can potentially offer a lower cost per kWh over the system's lifespan. ## About this series The Solplanet Ai-HB G2 (high-voltage, 7.5-20 kWh) is a modular energy storage solution designed to easily adapt its capacity to the actual needs of a home or small business. Its standout feature is the **segmented construction** - allowing for incremental expansion without replacing the entire battery, while the whole system operates under the control of a **highly advanced BMS with cell monitoring**, ensuring stable performance and extended lifespan. The applied chemistry, **LFP (LiFePO4)**, prioritizes safety: offering superior thermal resistance, high longevity, and predictable parameters over the long term compared to NMC solutions. In practice, this translates to reduced risks of overheating and better cost-effectiveness with frequent charging and discharging cycles. The declared number of cycles and the warranty provided here represent a genuine promise of multi-year operation - the more cycles, the longer the battery maintains its useful capacity. The **IP65-rated enclosure** also helps, simplifying installation outdoors. The Ai-HB G2 is designed for compatibility with **Solplanet hybrid inverters** (e.g., T2 and T3 series), making it suitable for grid-connected systems, self-consumption setups, and as a backup power element. ## Questions ### How many cycles can the Solplanet Ai-HB G2 withstand, and what is the manufacturer's warranty? The manufacturer claims 6,000 charging cycles at 80% depth of discharge (DOD) and 25°C, which translates to over 16 years of use with daily operation. The product warranty is 10 years. The LFP chemistry ensures slow and predictable capacity degradation, so the battery maintains its real-world utility for a long time without sudden performance drops. ### Is it possible to expand the storage capacity of the Solplanet Ai-HB G2 after installation? Yes, the modular design is one of the key advantages of this series. Each module has a capacity of 2.56 kWh, and the entire stack can be configured from 7.5 to 20 kWh. If energy demand increases, additional modules can be purchased without replacing the entire battery. With multiple stacks connected via a combiner box, the total system capacity can exceed 80 kWh. ### Which inverters are compatible with the Solplanet Ai-HB G2 battery? The Ai-HB G2 is designed to work with Solplanet hybrid inverters, primarily the T2 and T3 series. As it is a high-voltage battery, it requires an inverter that supports the appropriate DC voltage range from the battery side. It is advisable to confirm the exact compatibility with the existing inverter model with the installer before purchasing. ### Can the Solplanet Ai-HB G2 be installed outdoors? Yes. The Ai-HB G2 enclosure meets the IP65 sealing standard, which means complete protection against dust and water jets from all directions. This allows for installation in a garage, on an exterior wall, or in a technical shelter. However, it is recommended to avoid locations exposed to direct sunlight and extreme cold, in order to prolong the lifespan of the components. ### Why does the Solplanet Ai-HB G2 use LFP chemistry instead of NMC, and does this have any implications for safety? LFP (LiFePO4) cells are significantly more thermally stable than NMC cells - the risk of overheating or fire is much lower. With daily charging and discharging cycles, LFP cells degrade more slowly, which directly translates into maintaining their capacity throughout the declared warranty period. In the context of a home installation, this means less risk and a lower overall cost over the years of operation. ### Does the Solplanet Ai-HB G2 function as a backup power source when the main power supply from the grid fails? Yes, the Ai-HB G2 supports backup functionality when used with a compatible hybrid inverter from Solplanet. In the event of a power outage, the system switches to a standalone mode and provides power to selected circuits in the home using the energy stored in the battery. The range of protected devices depends on the inverter's power and the total capacity of the installed modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/batteries/d4fefccefb5c800273b06eb5.pdf) ## Alternatives | Battery | Usable energy | Round-trip | Power | Voltage | Difference | | --- | --- | --- | --- | --- | --- | | [SMA Home Storage 16.4](https://comparepv.com/battery/sma-solar-technology-ag-sma-home-storage-16-4) | 16.4 kWh | 94.5% | 17.3 kW | HV | +0.3 kWh, -0.5 pp round-trip, +6.5 kW | | [BYD Battery-Box Premium HVM 16.6](https://comparepv.com/battery/byd-battery-box-premium-hvm-16-6) | 16.56 kWh | 96.0% | | HV | +0.4 kWh, +1.0 pp round-trip | | [FoxESS HS17.5](https://comparepv.com/battery/foxess-hs17-5) | 16.68 kWh | | | HV | +0.6 kWh | | [FoxESS ECS2900-H6](https://comparepv.com/battery/fox-ess-ecs2900-h6) | 15.55 kWh | 95.0% | | HV | -0.6 kWh | | [Huawei LUNA2000-15-S0](https://comparepv.com/battery/huawei-luna2000-15-s0) | 15 kWh | | 5.0 kW | HV | -1.1 kWh, -5.8 kW | | [FoxESS ECS4300H-H4](https://comparepv.com/battery/fox-ess-ecs4300h-h4) | 14.93 kWh | 95.0% | | HV | -1.2 kWh | | [Deye GB-L16](https://comparepv.com/battery/gb-l16) | 14.72 kWh | | 16.4 kW | HV | -1.4 kWh, +5.6 kW | | [Deye GB-SL-EU (4 modules in series)](https://comparepv.com/battery/gb-sl-eu-4-modules-in-series) | 14.72 kWh | | | HV | -1.4 kWh | --- Source: https://comparepv.com/battery/solplanet-ai-hb-175a
