Off-grid Pure Sine Wave Inverter Charger Low Frequency 3000W 12V 85A Peak 9000W
Pure Sine Wave Inverter Charger. Volt Power Sinus 3000W 12V.
By a large input capacitor and switched On and Off by the Metal Oxide Silicon Field Effect Transistors (MOSFET) at a rate of 50 Hz or 60Hz, in this step the DC is converted to low voltage synthesized sine wave AC using an H-bridge configuration and high frequency PWM (Pulse Width Modulation) technique. It is then directed into the transformer which steps the low AC voltage up to 230 or 120 volts. The unit has a 16bit, 4.9MHZ microprocessor to control the output voltage and frequency as the DC input voltage and/or output load varies. Because of high efficiency MOSFETs and the heavy transformers, it outputs PURE SINE WAVE AC with low THD. The peak efficiency of DP series is 88%.You can connect solar panels , if you additionally use external solar regulator. Low quiescent current, low power Power Saving Mode to conserve energy. 4-step intelligent battery charger, PFC (Power Factor Correction) for charger. 8 pre-set battery type selector switch plus de-sulphation for totally flat batteries. Powerful charge rate of up to 120Amps, selectable from 0%-100%. 10 ms typical transfer time between battery and AC, guarantees power continuity. Smart LED remote control panel. 15s delay before transfer when AC resumes, extra protection for loads when used with generator. Allows start up and through power with depleted batteries. Extensive protections against various harsh situations. 13VDC battery recovery point, dedicated for renewable energy systems. It can work with all types of generators. The inverter can be customized to start up a generator when battery voltage goes low. When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the generator. Off after battery charging is finished. The auto gen start feature will only work with generators designed to work with this feature.
