Advance Notice Of MPPT 100A 300VDC

Dec 20, 2019

fangpusun FLEXmax 100 MPPT Charge Controller is now updated to have integrated arc fault circuit detection.  The advanced FM100 MPPT solar charge controller with AFCI eliminates ensuring less downtime and loss of PV production.  The algorithm offers increased energy harvest from the PV array than other MPPT controllers. The FLEXmax 100 delivers both higher voltage and higher power.


fangpusun FM100-300VDC solar controller is a top-of-the-line high performance, efficient and versatile charge controller for your advanced power system.  Additionally, there will be huge labor and cost savings from not needing the external combiner box up on the roof.



Improved: Integrated arc fault detection and interruption for optimized systems

Improved: 100A output for up to 6kW of charging with up to 7kW on the PV array

Improved: 300VDC open-circuit voltage limit enables up to 2-4 string configuration that minimizes BOS

Improved: Programmable auxiliary control output for smart load controls

Improved: Enhanced MPPT algorithm for increased energy harvest in harsh environments (ie. freezing temps, salty/dusty, or salty/marine areas)

Compatible with 24, 36 and 48VDC battery banks

Built-in and field replaceable arc fault circuit detection and interruption (AFCI), GFCI, and cooling fan

Minimum battery bank size, 100Ah

System configures quickly with smart programming wizards 

Monitor, command, and control over the Internet with OPTICS RE

Fully compliant with NEC 2017 RSD

2 Year Warranty (Upgraded to 7000W of solar power at 48V)
