Technical data

Model: WWS04-24-B00D / NE04-24-BOOD. Battery: 24V. Wind: 400W rated, 600W max. Solar: 200W (or custom). Max current: 17A. Net weight: 0.75 kg. Size: 123 × 150 × 62 mm. Origin: Jiangsu, China.

Wind control: shutoff 29V, restart 26.4V, brake current 17A.
Solar control: PV float charge 27V, anti-reverse yes, PWM yes.
Battery protection: over-discharge 21.6V, restart 24V, over-voltage 32V, anti-reverse yes.
Load 1 and Load 2: 10A per output. L1: 3 modes (default light control on/off). L2: 3 modes (default light control + 5 h timer off). Half power: yes.
Environment: −20°C to +55°C, humidity 35–85% non-condensing.

It handles wind and solar at the same time, protects the battery from overcharge, deep discharge and current spikes, brakes the wind generator when voltage or current is too high, dump-loads surplus energy and controls the load outputs by light, timer or constant run. Status is shown on LEDs and a digital display. Built for long life, low idle loss and stable operation in demanding climates.

Suited to 24V off-grid systems, small wind turbines (≤400–600W), solar and pole lighting, car parks, farms, marine sites, jetties, bathing places, outbuildings, barns, woodsheds and battery banks that need a high level of protection.
