Plasmatronics PV Hot Water Controller 100V 30A DC w/Element PLW

Sale price$1,340.00


The PLW is an MPPT controller for off grid PV solar hot water and grid boosted systems. PV hot water solves many difficult installation problems and can perform better than thermal solar hot water under many conditions. The PLW comes as a complete kit which includes a solar isolator, a low voltage heating element, two temperature sensors and a pre wired mechanical safety thermostat. The PLW takes information from two temperature sensors and displays it to the user. This information is also used to control the maximum tank temperature (thermostat function). The resulting system does not need boosting from other energy sources if an adequately sized PV Array is installed. The controller works with 60 cell and 72 cell panels.


No frost protection devices or pumps to fail. No roof reinforcement is needed. No battery required. Flexible: place tank near point of use and panels where convenient. Approved to the IEC62109-1:2010 safety standard.
