Product Briefing Outline: Xandex Solar, the solar products and services division of Xandex is launching the ‘SunMizer’ DC power optimizer for photovoltaic panels. SunMizer is a new DC power optimizer that increases solar energy harvest by recovering power that is lost when shade falls on a solar panel.
Problem: ‘Selective Installation’ gives SunMizer a claimed 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.
Solution: 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.
Applications: 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), 44V (VOC), and 9A (ISC) can be used with SunMizer It is compatible with most 208V and 240V residential size inverters.
Platform: 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 currently compatible with Uni-Rac Solarmount Standard and Lite, ProSolar Rooftrac, AEE SnapNrack and Unistrut racking systems. SunMizer is conected in-line with PV panels using standard series wiring schemes and does not require specialized wiring or “add-on” equipment. Each SunMizer unit will ship with a limited 20 year warranty that includes a provision for replacement labour.
Availability: Product shipments to the US will begin in Q1 2010.
