what is smd led? smd led stands for surface mount led. specifically, it's a light emitting diode that is mounted onto and soldered onto a circuit board. an smd led is quite small since it has no leads or surrounding packaging that comes with a standard led. this means it's best handled, not by a human, but by automated assembly equipment.
also, led (light emitting diodes) bulbs and energystar rated appliances consume less energy and operate more efficiently. you can therefore run more of these types of appliances on a sunrnr. appliances that run at 240v ac such as electric water heaters, cook stoves, furnaces and air conditioners, are impractical loads to run on solar whether generator or grid tie.
