EPSOLAR Applications (http://www.epsolarpv.com/c21548/default.asp): Street lights powerd by solar panels

As solar panels produce direct current (DC) that is then transformed into alternating current (AC) by an inverter. Most appliances are powerd by AC, so most systems have to use an inverter (or more than one). Some systems have a few loads that use DC, as well as the AC loads. And some systems are strictly DC and do not require an inverter. DC systems require special lighting, cables, appliances and equipment. Every our charge controller & inverter has very sophisticated technical features! See the text below what are they and their explanations:

1) Pulse Width Modulation (PWM) means to achieve constant voltage battery charging by switching the solar panels system. PWM regulation do the current from the PV array tapers according to the battery’s condition and recharging needs, and can greatly increase the lifetime of battery bank.

2) LVD function for solar charge controllers prevents low battery voltage from destroying the battery, the unit can be used to disconnect the load when it’s out of charge to prevent damaging it. Normal operation resumes immediately after PV charge controller recived some charge from solar panels.

3) Temperature compensation is an ability of the solar charge controllers to follow a battery capacity (stored charge varies with temperature). For optimum battery performance the charge controller needs to adjust its output voltage control to correspond to the needs of the battery as the temperature changes. A standard temperature co-efficient used by our charge controller is -5mv/ Deg C/cell.

APSOLAR has product Tracer as a solar charge controller (ideal for solar lighting system with two lamps that needs different timer setting) with MPPT technology: the TRACER utilizes Maximum Power Point Tracking (MPPT) technology to extract maximum power from the solar panel. The tracking algorithm is fully automatic and does not require user adjustment, tracking the array maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that maximum power is harvested from the array through the course of the day.
