Dyness PowerBox G2

Dyness PowerBox G2 is a battery that mounts on the wall, like a flat panel, and keeps the energy produced by the panels for the hours without sun. The enclosure is sealed, so it can also be mounted on an outside wall, in the rain. Inside it has an aerosol extinguisher that detects and smothers a possible fire within a few seconds, plus automatic pressure release.

Out of the 10.24 kWh, 9.728 kWh are usable, that is 95%, indicatively enough for the evening and the night of a home with average consumption. The usual working power is 5.12 kW, but if needed the battery can deliver 10.24 kW, that is it can on its own supply several large loads at the same time, with a peak of 300 A for 2 minutes. It is only 165 mm thick, at 710 x 640 mm and 99.7 kg, so it does not take up passage space, but it needs a solid wall. The declared service life is a minimum of 8000 cycles, respectively 10 years. It discharges between -20 and 55 deg C, and charging, normally possible from 0 deg C, goes down to -20 deg C if you choose the optional self-heating function.

LiFePO4, 51.2 V nominal, range 44.8-57.6 V, 200 Ah, 10.24 kWh nominal and 9.728 kWh usable at 95% DoD, minimum 8000 cycles. Rated charge/discharge power 5.12 kW at 0.5C (100 A), maximum discharge 1C — 200 A and 10.24 kW — with a peak of 300 A for 2 minutes at 25 deg C. IP66 enclosure of 710 x 165 x 640 mm and 99.7 kg, with an aerosol extinguisher that intervenes in about 5 seconds and automatic pressure release; discharge -20...55 deg C, charge 0...55 deg C, extended to -20 deg C with the optional self-heating function. CAN and RS485 communication, built-in WiFi with OTA updates, up to 50 units in parallel (512 kWh); declared compatibility with SMA, Schneider, Victron, Ingeteam, Solis, GoodWe, Growatt, Solplanet, Luxpower, Deye and APsystems, 10-year warranty.

Who it suits

Suitable for a home with average consumption where space is limited and the battery must sit on the wall, possibly outdoors, without protruding much into the room.

Terms explained

• 0.5C and 1C: The rate at which the battery gives or receives energy: 0.5C means emptying in about two hours, 1C in about one hour.
• OTA update: Updating the battery's internal software over the internet, without the installer coming on site with a laptop.
• Usable energy: The part of the capacity you can actually use: out of 10.24 kWh nominal, 9.728 kWh reach the loads.

Technical specifications

Recommended applications

• Wall-mounted residential storage, including outdoors
• Hybrid systems with Deye, Victron, Growatt, Solis, GoodWe inverters
• Simultaneous supply of several large loads in the home

Warranty

10 years
