The V1.5 specification lists 8 MPPT trackers, 16 PV inputs, a 200–950 V MPPT range and a 0–950 V DC output range, allowing PV voltage to be managed independently of battery voltage. It is a PV DC/DC controller, not a battery PCS. ## Key features - 200 kW PV DC/DC MPPT controller, wall-mounted IP65 enclosure - Step-up/step-down conversion; PV voltage can be configured independently of battery voltage - 8 MPPT trackers and 16 PV string inputs - PV open-circuit voltage 200–1100 V; MPPT operating range 200–950 V - DC output range 0–950 V; rated 700 V, maximum current 288 A - Maximum efficiency 99.26%; parallel operation supported; EMS RS485 and battery CAN/RS485 ## Description LEONA-M200K: 200 kW wall-mounted PV DC/DC MPPT controller The latest English V1.5 technical specification names the unit **LEONA-M200K MPPT Controller** and defines it as an IP65 wall-mounted step-up/step-down PV DC/DC controller for DC-coupled microgrids. It converts PV input to a controlled DC output. It is not a battery PCS or a standalone hybrid inverter. How the controller connects in a DC-coupled system PV strings enter the 16 PV terminals. Eight independent MPPT trackers control the PV channels, and the DC output connects to the system DC bus / compatible storage conversion equipment. The document notes that battery voltage is independent of PV configuration and that the output adapts to the battery-side DC voltage. Confirm control communications, allowable bus range and current sharing with the PCS or system integrator before combining models.
