Same as Mecer ( SOL-I-AX-5NB ) and KodaK ( OGX5.48 )

RCT Axpert MKS II is equipped with a 4,500 MPPT solar charge controller to maximize and regulate DC power from the solar array for charging the battery bank. Transformerless design provides reliable power conversion in compact size. Besides, its worry-free to start up motor-type loads such as refrigerators, motors, pumps, compressors and laser printers as well as electronic loads like TVs, Computers, power tool and battery chargers. Requires a minimum of 4 x 12V batteries.

Features:

• Pure sine wave inverter
• Output power factor 1
• Maximum PV array open voltage 450VDC 
• Maximum PV power 4500W
• Selectable input voltage range for home appliances and personal computers
• Selectable charging current based on application
• Configurable AC/Solar input priority via LCD setting
• Compatible to mains voltage or generator power
• Auto restart while AC is recovering
• Overload and short circuit protection
• Battery equalization for optimized battery performance and life-cycle
• Cold start function
• Parallel kit enabling parallel operation with up to 9 units 

Benefits over standard 5kVA MKS:

• Does not require a 4/5 string combiner box since the rated VOC means that all panels can be connected in a single string 450VDC (Saving approximately R4000)
• Fewer cables - lower cables costs 
• Lower voltage drop (ideal for installations where the panels and inverters are further apart
• 80Amp AC Charger - batteries can be charged faster from an AC supply
