Many Solar Charge Maximizing (SCM) controllers can work together to support a district scale solar power plant for a remote island, community, or village etc...
No grid power to remote community? No Problems! "SCM systems + Energy Storage" is the solution.
Following diagram shows a typical Micro-Grid System that is self-sustainable, and is supporting a remote community with or without backup power supply.
The mechanical contact switches in the solar charge maximizer controller system conducts high current solar power charging without generating heat from electronic components in the high current capacity of MPPT solar charge controller;
The strategically distributed Sub-Power-Stations are located near the solar panels to save the wiring cost between solar panels and the stations;
Many SCM systems are located in a single sub-station to save the cost for the temperature and humidity control in the sub-station;
The capacity of each grid-tie (local) inverter is limited to about 3.0~ 5.0 KW for high efficiency of the three-phase inverter;
Each SCM system has its own solar power storage capacity;
Maintenance to each sub-power-station has minimum impact on the whole micro-grid power supply to the whole community;
Following diagram shows the application details of each solar charge maximizing (SCM) controller system supporting the micro-grid power plant for a remote community.
