Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 4.8 kWh nominal (48 V) |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | 4.56 kWh |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | 95% |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LFP (lithium iron phosphate) |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | More than 8,000 cycles at 25 °C; design life 15+ years (the page does not state the end-of-life capacity) |
| ExpansionExtra battery units that add storage to the same system. | Up to 16 modules in a single string (about 76.8 kWh nominal) |
| Power | |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Normal 100 A; maximum 101-120 A for 15 minutes; peak 121-200 A for 15 seconds (about 4.8 kW normal at 48 V nominal; Pylontech gives amps) |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Not stated in the sources we read (Pylontech lists "high power efficiency" without a figure) |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Depends on the inverter: the battery itself is not an inverter |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None: this is the battery only. It needs a compatible inverter; Pylontech's page does not list models |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Not applicable: the battery connects to an inverter (48 V nominal, low-voltage DC) |
| Dimensions (W × D × H)Check the space before you buy, including room around it for airflow and cables. | 442 × 420 × 161 mm |
| WeightMatters for lifting, wall mounting and moving it. | 39.7 kg |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP20: for indoor installation; 19-inch rack compatible; humidity 5-95% without condensation; altitude below 4,000 m |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Charging 0 to 55 °C; discharging -10 to 55 °C; storage -20 to 45 °C |
| ConnectivityHow you monitor and control it, usually through an app. | RS485 and CAN |
| CertificationsSafety and grid standards the maker says the product meets. | UL1973, UL9540A, IEC 62619, IEC 63056, IEC 61000-6-2/3, UN 38.3 |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | Not stated in the sources we read |
Compatible with
What Pylontech says this product works with. Anything not listed here is not confirmed.
