SOLAR ELECTRONICS COMPONENTS
1. Charge Controller – between Solar Modules
and Battery
2. Inverter – between battery and loads
3. DC to Dc Converter – between battery and load
sum up: charge controller can serve the following
Purpose:
Prevention of over charging of battery otherwise
positive plate may damage due to gassing resulting
reduction of life of battery.
Prevent deep discharge of battery otherwise sulfation
may take place resulting in hardening of plates and
no charging of battery.
Provide status information for users.
Serve as wiring centre to load terminals battery and
solar module terminals
Important Technical Features and Characteristics
Output power and surge power
Maximum power rating of inverter depends upon the power
rating of the switches like transistor, Mosfet & IGBT etc.
For seconds till temperature rises inverter can bear the
surge of 200 to 300 percent of rated power only
Output efficiency
It depends upon switching loss of the transistors, wires, filters
& transformer at the output. The presently high efficiency
inverter available in the market of 94% efficiency.
Output wave form
It depend upon the switching technique of the power
transistors, pulsating types are easily manufactured not much
complication of design and they are cheaper and easily
available in the market but they affect the life of the appliances
operated.
