ECC now provides a solar controller that can be used for a wide variety of solar applications. Check out the Press Release (PDF) for all the exciting details.
The Model 510 is specifically designed to provide intelligent battery charging as well as control of a DC output such as a motor or DC lighting. An optional display provides a visual readout of battery voltage, photovoltaic voltage, load current and charging current. Without the display, four tri-color LEDs indicate the state of the battery, PV and curents.
The user can customize the unit to several different operating modes such as motor control based on battery state or night operation.
The unit can be factory configured for any of four different battery and photovoltaic arrangements e.g. nominally 12, 24, 36 and 48 Volt systems.
Solar systems with a battery operating a DC load are used in many situations where there is no easy access to electricity, or where it is desirable to work without being connected to the grid.
PV / Battery systems are very reliable and they produce power in all types of weather. On partly cloudy days, they can produce up to 80% of their potential energy. Even on extremely overcast days, they may still produce about 25% of maximum output.
