Solar Inverter 24V to 120V, 4KW PV Input, 450V VOC, Pure Sine Wave for Home, RV, Off-Grid

This 3000W Solar Inverter is a new off-grid power solution featuring a built-in 80A MPPT controller and 40A AC charger. It adopts full digital voltage and current double closed-loop control, advanced SPWM technology, and outputs a pure sine wave.

【TECHNICAL SPECIFICATIONS】This 3000W pure sine wave inverter converts 24V DC to 120V AC. It has a maximum PV input of 4000W, 450V(VOC), and 13A, with a maximum PV output of 80A. The AC input/output voltage is 120Vac±5%. The hybrid charging system allows a maximum combined charging current (AC charger+PV charger) of 80A.

【HIGH VOLTAGE PV INPUT】This is the high voltage version of the inverter, requiring a PV starting voltage greater than 150V. At least 4-6 solar panels are needed to start the inverter, with the exact number depending on the solar panel's open-circuit voltage. The high voltage version can handle up to 4000W of PV input power, while the low voltage version (100V max) is limited to 1600W.

【MULTIPLE CHARGING & LOAD MODES】The off-grid inverter offers four battery charging modes: Only Solar, Utility Priority, Solar Priority, and Utility & Solar Hybrid. It also has three load output working modes: PV Priority, Utility Priority, and Inverter Mode. These versatile options allow the system to be customized for different application requirements.

【USER-FRIENDLY INTERFACE】The 3000W inverter features an LCD display and 3 LED indicators that provide dynamic monitoring of system data and operating status. An intelligent variable-speed fan efficiently dissipates heat to extend the system's lifespan. This inverter can power a variety of household and office loads, including refrigerators, lamps, televisions, fans, and air conditioning.

【BATTERY COMPATIBILITY】This solar inverter activates both lead-acid (Seal, AGM, Gel, Flooded) and lithium batteries via PV solar or mains power, providing flexible battery options.

【SAFETY & PROTECTION】The inverter is designed with complete protection features, including short circuit, over/under-voltage, overload, and reverse polarity protection, ensuring safe and reliable operation.

【INSTALLATION & TROUBLESHOOTING】For PV to charge 24V battery banks, a minimum PV Voc voltage of 150V DC is required. The inverter does not support parallel operation or phase separation. A universal troubleshooting method is provided, involving step-by-step diagnostics to identify and resolve any fault codes.
