| manufacturer | Dyness |
| market_version | UNKNOWN |
| model | PowerBox G3 |
| mpn | UNKNOWN |
| product_family | Dyness PowerBox (PowerBox G2 / PowerBox Pro / PowerBox G3) |
| product_status | active |
| product_status_evidence | Listed on the dyness.com residential Low Voltage ESS index and has a live official product page, fetched 2026-09-02. |
| region | Global |
| release_year | 2026 (inferred: earliest located official datasheet revision is dated 2026-06-12 and page banner assets are dated 2026-06-04; no release year is printed) |
| sku | UNKNOWN |
| subcategory | low-voltage 48V-class wall/floor mounted battery |
| variant_note | Only one capacity/voltage variant (51.2 V / 200 Ah / 10.24 kWh) is published. |
Electrical
| cell_chemistry | LiFePO4 (LFP) |
| cell_type | UNKNOWN |
| continuous_charge_current_a | 100 (from 'Recommended C Rate 0.5C (100 A)') |
| continuous_discharge_current_a | 100 (recommended) / 200 (max, from 'Max Discharge C Rate 1C (200 A)') |
| continuous_power_kw | 5.12 (recommended charge/discharge power) |
| cycle_life | >=8000 cycles |
| depth_of_discharge_pct | 95 |
| max_charge_current_a | UNKNOWN (the table publishes a 'Max Discharge C Rate' but no maximum CHARGE C rate or current) |
| max_charge_power_kw | UNKNOWN (only 'Recommended Charge/Discharge Power 5.12 kW' is published; no maximum CHARGE power) |
| max_discharge_current_a | 200 |
| max_discharge_power_kw | 10.24 |
| max_parallel_units | 50 |
| max_series_units | N/A (LV parallel stack) |
| nominal_capacity_ah | 200 |
| nominal_energy_kwh | 10.24 |
| nominal_voltage_v | 51.2 |
| note | SAFETY-CRITICAL DISTINCTION: 'Recommended C Rate 0.5C (100 A)' is the recommended continuous rate; 'Max Discharge C Rate 1C (200 A)' is a DISCHARGE-only maximum; 'Peak Discharge Current 300 A, 2min' is a 2-minute peak. Dyness publishes NO maximum charge current or charge C rate for the G3, so the 200 A / 300 A figures must NOT be applied to charging. |
| operating_voltage_max_v | 57.6 |
| operating_voltage_min_v | 44.8 |
| parallel_supported | yes |
| peak_charge_current_a | UNKNOWN (only a peak DISCHARGE current is published) |
| peak_discharge_current_a | 300 (2 min) |
| peak_power_kw | UNKNOWN (300 A peak is published as a current, not as a kW rating) |
| round_trip_efficiency_pct | UNKNOWN |
| series_supported | no (low-voltage parallel-only architecture) |
| system_energy_max_kwh | UNKNOWN (not printed. 50 x 10.24 kWh would be 512 kWh, but the sibling PowerBox G2 page prints '50 units in parallel' alongside an expansion range ending at 409.6 kWh, which is 40 x 10.24 kWh - so the '50' figure is not a reliable basis for arithmetic on this family) |
| system_energy_min_kwh | 10.24 |
| usable_energy_kwh | 9.728 |
Physical / mechanical
| cooling_method | UNKNOWN |
| depth_mm | 165 |
| height_mm | 730 |
| installation_notes | 'Installation' = 'Floor-mounted, Wall-mounted'. |
| ip_rating | IP65 |
| mounting_type | ['floor', 'wall'] |
| rack_units | N/A (wall/floor enclosure) |
| weight_kg | 100 |
| width_mm | 710 |
Installation
| indoor_outdoor | indoor and outdoor (IP65) |
| installation_notes | UNKNOWN |
| mounting_orientation | floor-mounted or wall-mounted |
Environment
| charge_temperature_range_c | -20C to 55C ('Charge Temp. Range') |
| discharge_temperature_range_c | -20C to 55C ('Discharge Temp. Range') |
| indoor_outdoor | indoor and outdoor (IP65) |
| max_altitude_m | UNKNOWN |
| note | Unusually, the published CHARGE range starts at -20C, the same as the discharge range. That is only physically possible for LFP with an active heater, and the G2 page describes low-temperature charging as 'optional'. No heater is named in the G3 table - treat sub-0C charging as requiring confirmation from the datasheet. |
| operating_humidity | UNKNOWN |
| operating_temperature_max_c | 55 |
| operating_temperature_min_c | -20 |
| storage_temperature_max_c | UNKNOWN |
| storage_temperature_min_c | UNKNOWN |

| protocol_notes | No DIP-switch protocol table is published on the product page; the datasheet PDF is robots-blocked. |
| rs232 | UNKNOWN |
| rs485 | yes |
| usb | UNKNOWN |
| wifi | yes ('User Interface' = 'Wi-Fi + App') |
