Description
The range consists of two rating groups, 185–253 kW and 320–350 kW. The 800 V AC output is designed to work through a block transformer, and the higher voltage reduces the current and the AC cable cross-section across the large area of the plant. Depending on the model, the inverter has from 6 to 15 MPPTs with a current of up to 75 A, so powerful 182 and 210 mm format modules can be connected to a tracker. The IP66 housing is mounted outdoors on the array structures without a separate room. A scheme with string inverters instead of a central one simplifies repair, because the failure of one unit stops only part of the field.
How to choose
The rating is chosen by the power of the plant block and the transformer the inverters work into. The 185–253 kW group suits roofs and smaller sites, while 320–350 kW reduces the number of units on a large ground-mounted field. The number of MPPTs from 6 to 15 determines how finely the array can be split by orientation and shading. For a commercial roof connecting to a low-voltage grid, the smaller MAX/MAC KTL3 series is suitable.

FAQ
What is the output voltage of the MAX 185–350K-X HV inverters?
800 V AC. The inverters connect to the grid through a transformer, and the higher voltage level reduces the currents in the AC lines.
How many MPPTs do the MAX K-X HV series inverters have?
From 6 to 15 depending on the model, with up to 75 A per tracker.
Is the MAX 185–350K-X HV suitable for 210 mm modules?
Yes, the MPPT input current of 75 A is designed for powerful 182 and 210 mm format modules with a high operating current.
What is the efficiency of the MAX 320–350K-X inverter?
Maximum efficiency is 99.03 %, which noticeably reduces annual losses at a plant of hundreds of kilowatts.
Can the MAX K-X HV be installed outdoors?
Yes, the IP66 protection rating means full protection against dust and powerful water jets, so the inverter is fixed to the array structures.
