3000W 48 V low-frequency pure sine wave inverter‑charger with a built-in 35 A battery charger and a 9000W peak power rating, designed for off‑grid, marine, caravan and backup use.

• Power: 3,000W continuous (nominal), 9,000W peak.
• Input: 48 V DC. Output voltage: 208 V / 220 V / 230 V / 240 V (programmable). Output frequency: 50Hz / 60Hz / auto (programmable). Output wave: pure sine wave.
• Battery charging: fast built-in charger with selectable 7 A / 14 A / 21 A / 28 A / 35 A options and advanced 4‑step progressive charging; charger can be switched off.
• Battery bank type: sealed lead acid, gel (programmable settings). Input voltage range: normal or wide (programmable).
• Modes & efficiency: nominal inverter efficiency 88%; power saving mode; UPS and bypass mode; AC / DC priority mode.
• Protections & alerts: protection against overload, overheat, low battery and overcharge. Minimum battery voltage 40 V; low battery alert 42 V; overcharge protection voltage 62.8 V. Power factor: 0.9–1.0.
• Physical & environment: Weight 26 kg (57.3 lb). Size 44.2 x 21.8 x 17.9 cm (17.4 x 8.6 x 7.0 in). Operating temperature range 0–40°C (32–104°F).
• Suitable for running appliances: pure sine wave output is suitable for a broader range of appliances (modified sine wave inverters cannot power, for example, appliances with electric motors) and is more compatible and gentler on sensitive electronics.
• Warranty & documentation: This product is covered by a 1-year manufacturer warranty. User manual for the 3000W 48 V pure sine wave low frequency inverter‑charger with charger is available to download.
