Typical AC-coupled systems from competitors achieve 88-92%, which translates into measurable savings over a year with a high self-consumption rate. - **LFP battery with unlimited cycle life under warranty** - The LiFePO4 chemistry provides thermal stability (no risk of thermal runaway) and a 10-year warranty with a capacity retention of ≥70% after an unlimited number of cycles (without a counter, such as in BYD Battery Box HVM with a limit of approximately 6,000 cycles or energy of MWh). The user can charge and discharge the battery daily without incurring any contractual penalties. - **Modular design, up to 23 kWh** - A single module provides a usable capacity of 4.6 kWh; up to 5 modules (approximately 23 kWh total) can be connected to a single inverter without requiring an inverter replacement. Starting in January 2025, modules connected to new Home Hub Three Phase installations will have an increased capacity of 4.85 kWh, which improves the cost-effectiveness of expanding existing installations. - **Power output of 4,096 W per module** - A single module offers a continuous discharge power of 4,096 W, while multi-module configurations provide a continuous power of 5,000 W (for both charging and discharging). This is sufficient to power typical household appliances in a backup mode without the need to purchase a separate isolated inverter. - **Integrated SolarEdge monitoring** - The battery operates natively within the mySolarEdge ecosystem - data from the PV system, battery, and grid are visible in a single application without the need for integration via third-party protocols (Modbus TCP, CAN). This simplifies maintenance and diagnostics compared to solutions from different manufacturers. ### Cons - **Vendor lock-in - only SolarEdge** - The battery is compatible exclusively with SolarEdge Home Hub / StorEdge Three Phase inverters. Replacing the inverter with a different brand or switching to a hybrid inverter from another manufacturer requires replacing the entire energy storage system, which significantly increases the investment risk over a 10-year lifespan. - **The backup mode requires an additional module.** - Backup power is not available out-of-the-box and requires the purchase and installation of a separate SolarEdge Home Backup Interface. This results in additional hardware and installation costs compared to competitors (e.g., Huawei LUNA2000 with a built-in backup function in the SUN2000 hybrid inverter). - **Price of approximately €396/kWh, which is above the market median.** - Module 4.6 kWh at a price of approximately €1,824 (ONSA Plus, May 2025) results in an average user cost of approximately €396/kWh. The BYD Battery Box Premium HVM offers a comparable LFP capacity in the range of €300-€350/kWh, which represents a SolarEdge premium of 13-32%. For installations that do not require the SolarEdge ecosystem, this premium may be difficult to justify. ## About this series The SolarEdge Home Battery 48V (Europe) series consists of modular DC energy storage systems designed for seamless integration within the same ecosystem as SolarEdge Home Hub and StorEdge (three-phase) inverters. The main advantage is **direct DC coupling**, enabling excess PV energy to reach the batteries without unnecessary conversions, thereby significantly improving the overall system efficiency and backup power quality. The implemented chemistry, **LFP (LiFePO4)**, prioritizes thermal safety, stable long-term operation, and high tolerance to intensive use - which is crucial both in homes and small businesses. In practice, this translates to **a high number of cycles** and **a long manufacturer warranty**, reducing costly replacement risks and ensuring predictable operation for years. The system is **scalable** - additional modules can be easily added as demand increases, without the need to replace the entire installation. This solution is ideal for on-grid with self-consumption, hybrid systems with backup power, and projects requiring unified monitoring within a single application. ## Questions ### How much energy can be stored in the SolarEdge Home Battery 48V system, and is it possible to expand it? One SolarEdge Home Battery 48V module offers a usable capacity of 4.6 kWh at 100% depth of discharge. The system is modular - you can connect 1 to 5 modules per inverter, resulting in a total capacity of up to 23 kWh. Expansion does not require replacing the inverter or the entire system; simply add another module as your energy needs increase. ### What is the warranty on the SolarEdge Home Battery 48V, and what exactly does it cover? The manufacturer provides a 10-year warranty on the SolarEdge Home Battery 48V series. The warranty terms stipulate that the battery must retain at least 70% of its nominal capacity at the end of the warranty period. Importantly, SolarEdge does not impose a limit on the number of charge cycles - the battery can be used intensively throughout the warranty period without the risk of it being rendered unusable due to exceeding the permitted number of cycles. ### Which inverters are compatible with the SolarEdge Home Battery 48V, and does it work with my existing SolarEdge system? The SolarEdge Home Battery 48V series is designed to work with SolarEdge Home Hub and StorEdge (three-phase) inverters. It is not compatible with single-phase SolarEdge inverters or devices from other manufacturers. If you already have a Home Hub or three-phase StorEdge inverter, integrating the battery is straightforward and does not require additional DC-to-AC converters. ### Does the SolarEdge Home Battery 48V provide backup power during a grid outage? Yes, the system supports a backup mode, but this requires a dedicated SolarEdge Home Backup Interface module and a three-phase Home Hub inverter. This feature is subject to local legal regulations, so it is advisable to confirm its availability with the installer. The DC connection ensures that energy from the PV panels reaches the batteries and loads without unnecessary conversions during a power outage, which improves the quality of power. ### Why does the SolarEdge Home Battery 48V use LFP chemistry instead of the more common NMC batteries? LFP (LiFePO4) chemistry is thermally safer than NMC - it does not self-ignite even with mechanical damage or deep charging. LFP batteries degrade more slowly during daily charging and discharging cycles, which translates to durability that meets the 10-year warranty. The trade-off is a slightly lower energy density (larger volume for the same capacity) and operation at 48V instead of higher voltages used in NMC systems. ### What is the performance of the SolarEdge Home Battery 48V system, and does the DC coupling actually make a difference? The overall efficiency of the charging and discharging cycle (roundtrip) exceeds 95.4%. DC-coupled operation means that energy from solar panels is transferred to the battery without prior conversion to alternating current (AC) and back to DC, saving 2-5% of the losses typically associated with AC-coupled systems. In practice, with high self-consumption and daily cycles, this translates to significantly lower electricity bills over the course of a year. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/batteries/560c153bfc065368e2b5ddae.pdf) ## Alternatives | Battery | Usable energy | Round-trip | Power | Voltage | Difference | | --- | --- | --- | --- | --- | --- | | [Deye AI-W5.1-B (1 module)](https://comparepv.com/battery/deye-ai-w5-1-b-1-module) | 4.6 kWh | | 9.2 kW | LV | +4.2 kW | | [Dyness DL5.0C](https://comparepv.com/battery/dyness-dl5-0c) | 4.61 kWh | 90.0% | 2.6 kW | LV | -5.4 pp round-trip, -2.4 kW | | [FelicityESS LUX-E-48100LG03](https://comparepv.com/battery/felicityess-lux-e-48100lg03) | 4.86 kWh | | | LV | +0.3 kWh | | [Deye SE-F5](https://comparepv.com/battery/deye-se-f5) | 4.1 kWh | | 6.1 kW | LV | -0.5 kWh, +1.1 kW | | [Deye SE-F5 Plus](https://comparepv.com/battery/deye-se-f5-plus) | 4.1 kWh | | 6.1 kW | LV | -0.5 kWh, +1.1 kW | | [Deye SE-F5 Pro](https://comparepv.com/battery/deye-se-f5-pro) | 4.1 kWh | | 5.1 kW | LV | -0.5 kWh | | [Deye SE-G5.1 Pro-B (EU, NA, AU)](https://comparepv.com/battery/deye-se-g5-1-pro-b-eu-na-au) | 5.12 kWh | | 5.1 kW | LV | +0.5 kWh | | [Deye RW-L5.1](https://comparepv.com/battery/rw-l5-1) | 5.12 kWh | | 5.0 kW | LV | +0.5 kWh | --- Source: https://comparepv.com/battery/solaredge-bat-05k48-single-module
