Axpert MKS-II 5kW (48V)

Designed in Taiwan, Axpert is a brand of the world’s largest OEM battery inverter manufacturer with more than 100,000 Axpert Inverters produced annually.

The 2nd Generation Axpert MKS-II combines the functions of an Inverter/Charger for grid backup with a 80A MPPT Solar Charge Controller for PV generation into one wall-mount 11kg enclosure.

With a Power Factor of 1, it’s 5kVA rating provides 5kW of Pure Sine Wave continuous output (10kW surge rating). And it’s 80A (4kW) AC charging rate is ideal for grid-backup as it can rapidly charge batteries, and it’s wide AC input voltage is compatible with a generator on a change-over switch so the backup genset can be used to charge batteries.

 Scalable Capacity, Single or Three Phase

Up to 9 units can be connected in parallel to a central battery bank with 45kW single phase output and PV or Grid charging of up to 36kW. Systems can also be connected in multiples of 3 for 3-Phase power. In either arrangement, battery storage is centralised.

Note: MKS-II Parallel Kit required for this.

 Easy PV String Design

Axpert’s wide MPPT range (120-430V) and high maximum DC input voltage (450V) maximises flexibility of PV string design, permitting all PV panels to be placed in series. The integrated 80A MPPT Solar Charge Controller provides 4kW of PV charging but with its 450V Open Circuit Voltage up to 4.5kWp of PV can be connected to allow for temperature losses.

 Uninterrupted AC Power (UPS Function), down to 10ms Response Time

In the event of power cuts, the MKS-II’s inverter is automatically activated and supplies 5kW of back-up power to connected loads. The default response time is 20ms (with AC input voltage of 90-280V AC) but can be configured to 10ms (with a narrower AC input voltage of 170-280V) for computers and other sensitive electrical equipment.

 Compatible with Pylontech Lithium batteries and Lead Acid

All Axpert inverters support lead acid with adjustable voltage values as well as a range of Battery Equalisation settings for flooded batteries.

Pylontech lithium batteries, capable of up to 6000 cycles and fast 0.5C charge rate, do not require RS-485 or CAN communication to the inverter for their 10 year warranty (See downloadable Voltage values). However, communication between the inverter and lithium battery does result in more stable performance and prevents batteries from having to be physically reset when empty.
