Description
The range has three versions, Knight 3600-24, 3600-48 and 6000-48, where the second number is the battery voltage, 24 or 48 V. Lead-acid and LiFePO4 batteries are supported. The PV input accepts Voc up to 500 V and the MPPT working range is 120–450 V, so the module string is sized to fit these limits. The total charge current from PV and grid reaches 120 A. Efficiency is up to 93.5 %. The enclosure is rated IP21, so the unit goes in a dry room, not on an open site. Up to 6 inverters run in parallel, which is how the capacity of a site is increased.
How to choose
Start with the battery voltage. The 3600-24 suits a small 24 V battery, while the 3600-48 and 6000-48 pair better with a 48 V battery, where the current is lower at the same power. The 3.6 or 6 kW rating has to cover the peak current of the loads, and when there is not enough margin, up to 6 inverters are paralleled. If you need grid-tied operation instead of off-grid, look at BluE-G at 1–6 kW or the three-phase BluE at 3–25 kW.

FAQ
Which batteries does the Knight inverter support?
Lead-acid and LiFePO4 at 24 or 48 V depending on the version. The 3600-24 is built for 24 V, the 3600-48 and 6000-48 for 48 V.
What are the MPPT range and the maximum PV voltage?
The MPPT range is 120–450 V, and the open-circuit voltage Voc must not exceed 500 V.
How many Knight inverters can be connected in parallel?
Up to 6 inverters. This raises the power above the 3.6 or 6 kW of a single unit.
What is the maximum battery charge current?
Up to 120 A, which is the sum of the current from the PV modules and from the grid.
Can the inverter be installed outdoors?
IP21 is too low for an open site. The unit is installed in a dry room.
