Season Greeting Everyone,
Finally, the 10KW Solar Charge Controller was tested in a facility in Bangalore. Honestly, the facility in Bangalore did not have a proper 10KW system. So, we were restricted to only test upto 8KW.
Our Solar Charge Controller is designed with the mentioned specifications: -48V, 200A (yes, it is negative 48 Volts). The facility in Bangalore had a capacity to only run the system at 160A and was refusing to go beyond the ampere rate.
Few observations of the system during testing: the temperature rise was quite moderate for the power components used. The max. temperature recorded was about 60 degree Celsius. The temperature was recorders using Thermal Sensor with Fluke system which was connected to a PC through Serial Port.The Hyrda Software designed for Fluke Company was recording the temperature of all the power components in the Charge Controller for interval of 600 seconds.
Second key observation is the the wires that were used to the interconnect the whole Charge Controller. The theoretical knowledge generally around is that for 1 sq. mm of copper wire, we can use it for 10A rating. Well, that was quite false and proven by the test. We approximated the rating to 3A-4A per sq. mm of copper wire.
Well, we are already on the move to construct the next system with better enhanced heat-sinks to dissipate the heat faster and better, improved looks and far better design.
We are welcome to accept commercial requests as this Charge Controller is designed for Telecomm products and may not be suitable to all. Please feel free and send us requests or suggestions.
