Recovers over 50% of power loss due to shade
SunMizer DC Power Optimizer
SunMizer™ is a new per-panel DC-to-DC power optimizer that performs MPP tracking at the panel substring level to increase power harvest. SunMizer achieves maximum power flow from the panel during sub-optimal module operating conditions caused by shade and soiling to recover over 50% of system level power loss.
SunMizer's patent pending Optimum I-V for PV™ technology combines simple design with the fewest, most robust power components available. The result is best in class reliability and performance in the most effective efficiency improvement solution available for PV.
Improved Roof Utilization and Aesthetics
With SunMizer, the system designer can now install more panels and increase system power production (see Design Guidelines). Panels can now be placed on roof space that would not have been utilized in the past because panels in these areas would actually decrease system output. In addition, SunMizer optimized panels can be installed in locations to match the roofline, avoiding odd shapes and cut-outs. This makes for a more attractive and aesthetically pleasing solar array. More power with an attractive system, a win-win for the system owner and the designer.
"Selective Installation" gives SunMizer a unique advantage over competing DC/DC power optimizers that require a unit on each panel in a string. SunMizer can be installed selectively, only on the solar panels that experience regular shade or soiling. Selective installation provides optimized power output at a lower initial cost and that means faster return on investment for the system owner.
Compatibility and Installation
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 panel racking with standard rack system fasteners and nuts. Each unit has an integral grounding lug that also accepts a ring terminal connection. SunMizer is connected in-line with PV panels using standard series wiring schemes and does not require specialized wiring or "add-on" equipment.
SunMizer is currently compatible with many rack systems including;
- Unirac Solarmount Standard and Lite,
- ProSolar Rooftrac
- AEE SnapNrack
- DPW POWER-FAB
- Schletter
- Unistrut
SunMizer is compatible with a large list of 156mm cell architecture models from most major panel manufacturers worldwide. Panels with a maximum power rating of 250W (Pmax), 48V (VOC), and 9A (ISC) OR350W (Pmax), 80V (VOC), and 7A (ISC) can be used with SunMizer (see SunMizer Compatibility Calculations). SunMizer is compatible with most 208V and 240V residential size inverters.
SunMizer is designed to last the lifetime of any solar installation and built with the finest long-life components and materials. A weatherproof NEMA 6 (IP 67) enclosure ensures that the unit will not be affected by dust intrusion, water or ice. Each unit is covered by a 20 year warranty that includes a replacement labor provision (see product warranty for full details).
SunMizer is certified to the UL 1741 safety standard and is compliant with FCC part 15 Class B emissions standard. SunMizer is also certified to the European CE and GS safety standards. All SunMizer components are RoHS compliant (lead, mercury and cadmium free).
SunMizer is built in the USA by the solar products division of Xandex Inc. Since 1981, Xandex has designed and manufactured products used in the exacting semiconductor test industry. SunMizer is designed and tested to rigorous Military and Telecomm quality standards that insure the highest level of quality, performance and long life.
