SUNGOLD 4000W DC 24V Pure Sine Wave Inverter with Charger
- This Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch. Low frequency, low Idle Current, BTS cable, remote control.
- Adjustable Charging Current: The max charge current can be adjusted from 0%-100% via a liner switch on the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank.The liner switch can effectively reduce the max charging current to 20% of its peak.Choosing “0” in the battery type selector will disable charging function.
- AC/Battery Priority: Our inverter is designed with AC priority by default, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. The inverter can be easily customized to Battery priority via a DIP switch, When you choose battery priority, the inverter will invert from battery despite the AC input.
- Auto Gen Start: the inverter can be customized to start up a generator when the 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.
- Protections: AC input over voltage protection/AC Input low voltage protection/Low battery alarm/High battery alarm /Over temperature protection/Over load protection Short Circuit protection (1s after fault) /Back feeding protection.
Main Features:
- 4000W Low Frequency Pure Sine Inverter With Charger.
- AC/Battery Priority Selector.
- Automatic Generator Start.
- Safety and Convenient.
- The low frequency inverter can power all kinds of appliances.
- LCD Display, Remote Control, BTS including.
