SunMizer is a new per-module DC-to-DC power optimizer that performs MPP tracking at the PV module substring level to increase array power harvest. SunMizer achieves maximum power flow from the module during sub-optimal module operating conditions caused by shade and soiling to recover more than half of system level power loss. Modules can now be placed on roof space that would not have been utilized in the past because modules in these areas would actually decrease system output. In addition, SunMizer optimized modules can be installed in locations to match the roofline, avoiding odd shapes and cut-outs.
Use one on each module that will be shaded
Selective installation gives SunMizer a unique advantage over competing DC power optimizers that require a unit on each module in a string. SunMizer can be installed selectively, only on the solar modules that experience regular shade or soiling. Selective installation provides optimized power output at a lower initial cost than a fully installed solution. SunMizer is lightweight (< 2 kg) and its compact dimensions of 6" x 4" x 1.6" (15 x 10 x 4 cm) make it easy to install directly to module racking with standard rack system 5/16 or 1/4 inch fasteners. Each unit has an integral grounding lug that also accepts a ring terminal connection. SunMizer is connected in-line with PV modules using standard series wiring schemes and does not require specialized wiring, or add-on equipment. SunMizer is compatible with solar modules that have 54-60 156m m cells. Modules with a maximum power rating of 250W (Pmax), no more than 48V (Voc), and 9A (Isc) can be used with the SunMizer. SunMizer is compatible with most 208V and 240V residential size inverters. SunMizer is made in the U.S. TUV certified to the UL 1741 safety standard. 20-year warranty includes a replacement labor provision.
