200W, solar to 48v or 36v battery, Step Up DC/DC Converter
Using Boost Converter Topology,& optimized single direction current, this product is used to charge a 36 or 48v battery.It is connected to the solar panel and the battery.
The Optimizer does three things:
1) Steps up the voltage.
2) Charges the battery.
3) Optimizes the power.
1) Steps up the voltage. IE when using a 36v battery and a maximum voltage during peak suns of 26.3v, the optimizer steps up and charges the battery.
2) Charges the battery. If the battery is a 36vdc lead acid, the charging voltage of 43.2vdc is set with the blue pot shown below. You can set the pot anywhere from 40 to 56 vdc. If the pot is set at 43.2vdc and the voltage is met, the unit shuts down and no current flows. When the temperature compensated voltage of the battery is reached, the blue pot sets this, the unit shuts off. No battery power is used to power the optimizer. All the power comes from the solar panel.
3) Optimizes the power. The power is calculated every 1/2 second. The pulse width modulation is changed, if needed, every 1/2 second. At low powers, when the sun is weak, even one watt is transferred to the battery. One watt is only .025 amps at 40vdc. At higher powers, like 200 watts, 5.0 amps is charging the battery.
