Power converter systems

A method for managing power supply in a power converter system, the method comprising:

• receiving, via an alternating current (AC) input interface, an AC power input at a battery charge controller of the power converter system;
• converting, using the battery charge controller, the AC power input into DC power and supplying this to a battery within the system;
• determining, using a microcontroller, a first power requirement for a load;
• establishing, using the microcontroller, whether the power input is less than the first power requirement for the load;
• and
• powering, responsive to the determination that the power input is less than the first power requirement for the load, the load using a combination of the power input and a supplemental power supply from the battery, wherein the DC power from the battery is converted back to AC power using a phase inverter in the power converter system.

A device for managing power supply in a power converter system, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:

• receive an alternating current (AC) power input at a battery charge controller of the power converter system;
• convert the AC power input into DC power and supplying this to a battery within the system;
• determine a first power requirement for a load;
• establish whether the power input is less than the first power requirement for the load;
• and
• power, responsive to the determination that the power input is less than the first power requirement for the load, the load using a combination of the power input and a supplemental power supply from the battery, wherein the DC power from the battery is converted back to AC power using a phase inverter in the power converter system.
