3000W 12V Low-Frequency Pure Sine Wave Inverter – 9000W Peak | 4Boats

3000W 12 V low‑frequency pure sine wave off‑grid inverter with built‑in 90 A battery charger and 9000W peak output for demanding starts.

• Power rating: 3000W nominal, 9000W peak (short duration); nominal inverter efficiency: 88%; Power factor: 0.9–1.0.
• Input: 12 V DC. Output voltage: 208 V / 220 V / 230 V / 240 V (programmable). Output frequency: 50Hz / 60Hz / auto (programmable). Output wave: pure sine wave.
• Input voltage range: normal or wide (programmable). Battery bank type: sealed lead acid, gel and other selectable types. Battery charging current options: 18 A / 36 A / 54 A / 72 A / 90 A (programmable).
• Fast built‑in battery charger with advanced 4‑step progressive charging and selectable battery types; 90 A max charging current option available.
• Modes: power saving, UPS and bypass, AC / DC priority. Minimum battery voltage: 10 V. Low battery alert: 10.5 V. Overcharge protection voltage: 15.7 V.
• Protections include overload, overheat, low battery and overcharge to safeguard the inverter and connected loads.
• Suitable for a broader range of appliances than modified sine wave inverters (modified sine wave units may not power appliances with electric motors); ideal for motorhomes, caravans, boats, farms and remote off‑grid or backup use.
• Operating temperature range: 0–40°C (32–104°F). 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). Covered by a 1‑year manufacturer’s warranty.

For best results, match the inverter to a suitably sized battery bank and follow the manufacturer’s installation and maintenance guidance; compatible with common 12 V battery chemistries when charger settings are selected appropriately.
