Any-Grid PSW-B — off-grid inverter-charger 0.5–3 kW
Country: Germany · Model: Any-Grid PSW-B
The Any-Grid PSW-B is a compact off-grid inverter-charger rated from 0.5 to 3 kW for 12 or 24 V banks. The output is a pure sine wave of 110–240 V, and the built-in MPPT controller accepts up to 1800 W from solar modules. The series is used in cottages, guard huts, telecom cabinets and small off-grid solar plants that do not need to feed energy into the grid.

Description
Inside, an inverter, a solar MPPT controller and a charger are combined; the charger tops up the battery from the grid or a generator when sunlight is short. The unit does not feed energy into the grid, and the grid or generator serves only as a charging source. The solar input accepts up to 145 V DC, so modules can be connected in series in short strings to reduce the cable current. The peak efficiency on battery power is above 90–93 %, depending on the model. The output voltage stays within ±5 %, which suits pumps, refrigerators and electronics. The IP21 enclosure is hung on a wall in a dry room next to the battery so that the DC cables stay short. The device carries CE and RoHS marking.
How to choose
The main factors are the bank voltage and the grid voltage. PSW-B-1KW-230/12V and PSW-B-0.5KW-120/12V are designed for 12 V, while PSW-B-1.6KW-120/24V and PSW-B-3KW-230/24V work at 24 V. Versions with index 230 have an output for 230 V grids, and those with index 120 for 120 V grids. For loads above 3 kW or for parallel operation, switch to the hybrid Any-Grid PSW-H (3–8 kW) with a 24 or 48 V bank, which can be combined in groups of up to 9 units.

FAQ
How much solar panel power can be connected to the Any-Grid PSW-B?
The upper limit for the series is 1800 W at a string voltage of up to 145 V DC. For the smaller models, check the value against the datasheet of the specific version.
Does the PSW-B inverter feed energy into the grid?
No, it is an off-grid unit. The grid or a generator only charges the 12 or 24 V battery through the built-in charger.
What battery bank voltage do the different PSW-B models require?
The 0.5 and 1 kW models work with a 12 V bank, and the 1.6 and 3 kW models with a 24 V bank. The version is easy to match to batteries you already have.
What efficiency does the PSW-B have when powered from a battery?
The peak efficiency from the battery exceeds 90–93 %, depending on the model. These losses are included in the bank capacity calculation for night consumption.
Where should the PSW-B with IP21 protection be mounted?
Only in a dry room without condensation, for example a technical room or a cabinet. Outdoors, an additional protective box is required.
