APEX MPPT-4K
An MPPT Charge Controller's primary function is to charge batteries from solar panels by tracking the Maximum Power Point.

The APEX MPPT-4 was designed to help minimise total photovoltaic system capital and lifetime operational costs through a variety of innovations:
Features include:
Two Independent MPPTs: The APEX MPPT-4 contains two fully independent MPPTs, perfect for residential applications where PV arrays often face in a variety of directions. Connecting such PV strings to separate MPPTs can increase energy yields significantly compared to combining all strings into one MPPT.
Wide PV String Voltage Range: Each of the two MPPTs can accept PV string DC voltages between 65 and 375V. This 65V 375V wide range means a single PV string per MPPT is possible, instead of being forced to parallel PV strings. This allows for thinner DC cables, no string junction boxes and easier & lower cost installations.
Integrated Protection: The APEX MPPT-4 includes as standard a variety of protection designs, ensuring safe operation and easy & cost effective compliance to applicable regulations. These include Ground Fault Detect and Interrupt, which is becoming a regulatory requirement in most countries.
Compatible With Various Battery Technologies: Unlike many MPPTs, the APEX MPPT-4 is compatible with a variety of battery technologies. For example, in the event of a li-ion battery trip, the APEX MPPT-4 will immediately disconnect, thereby protecting against rapid battery DC bus rises which typically destroy slower MPPTs and connected inverters. The APEX MPPT-4 charging voltage and current are fully adjustable, and it can communicate via CAN bus (optional).
