KEVIN Solutions is based in Uttar Pradesh (India) and they are the manufacturers of power back-up systems (Inverters, UPS), Batteries & Solar systems. Their website says that their facilities are ISO 9001:2000 certified.
KEVIN manufactures the following systems for solar power: Solar Power Conditioning Unit (SPCU), Solar Grid Interactive, Solar Charge Controllers & Solar Motor Pump Drives.
Solar Power Conditioning Unit (SPCU) is an interesting concept as each SPCU has built-in solar panels, inverter, grid-charger and charge controller! Customers only need to buy batteries additionally, if they want to store the generated solar power.
Solar Grid Interactive is a system that exports excess power generated by solar panels to the grid (mains) and imports power from the grid when solar power produced is insufficient. The grid is used like a remote battery and hence, if the electricity provider supports this technology (and buys power from customers), batteries can be eliminated.
KEVIN also supplies solar charge controllers and solar motor pump drives.
