• Projecta Inverter Chargers support universal LFP charging profile and offered pre-defined LFP charging profile for Projecta HD series lithium batteries.
• Built-in BMS pre-defined LFP charging and communication for LBXXX-HD series batteries.
• According to cell temperature and real-time SOC, BMS will send commands to the battery charger asking for optimum charging voltage and current.
• This synchronization will prevent overheating or overcharging, especially at the end of charging, to extend the life of the battery.
• Instead of using voltage as protection, SOC value is used to avoid permanently damaging lithium batteries due to being left discharged for a long time.

AC Transfer Switch

• In case of poor AC mains power (due to poor voltage/ frequency or waveform characteristics, the Inverter

The charger will switch to inverter and battery power.

• In case of AC mains failure or exceeding the maximum AC input current set by the user, the Inverter
• The charger will initiate a quick switch to the inverter, which will guarantee continuous power. When stable AC power is resumed, the inverter charger will switch back to AC mains power after a 5-second delay.
• Due to its ultra-quick transfer design, as quick as 0ms.
• The Inverter Charger could be used as a UPS.

Ground Relay

• The neutral output of the Inverter Charger is automatically connected to the earth upon no external AC sources are available. Once external AC sources are present, the ground relay will open. The Ground relay is required for the RCD to function correctly.

Protections and Safeguards

• The Inverter Charger is equipped with a series of complete hardware and software protection functions to ensure its stable and reliable operation.

Overload protection

• When overload protection is triggered, it will restart automatically after the 60s. After three consecutive overload shutdown protections, the equipment will not restart automatically. At this time, the user needs to manually restart.

Over temperature protection

• When the internal temperature is too high, the Inverter Charger will enter into the over-temperature protection. After the internal temperature returns to normal, it can automatically resume normal operation.
