DESCRIPTION:

The solar regulator is the connecting part between the 12V lead battery and the photovoltaic panel. MPPT controls the charging of the battery from the photovoltaic panel and searches for the point between voltage and current where the energy consumption from the photovoltaic panel is greatest at a given moment (Maximum Point Power Tracking or MPPT). A modified perturbation principle (MP&O) of maximum power search is built into the device. With MPPT, it is possible to get about 30% more power from the photovoltaic panel, unlike the situation when the battery is connected directly to the photovoltaic panel. In addition, the MPPT ensures (during long periods of sunshine and low battery power consumption) that there are no side effects of overcharging the battery.

APPLICABLE TO:

The MPPT without housing is intended for mounting in an electrical distribution box. It can be an integral part of 12V systes (in environments without mains voltage) such as:

• an electric shepherd
• a remote measuring station
• smaller holiday cottages
• traffic sign
• emergency lighting
• sailboat & boat
• campers & caravans
• automatic solar watering ...

STATUS ON LCD:

The values of voltage and current of photovoltaic panel and battery are displayed on the screen during operation of the MPPT-1000 solar controller.

SERIAL COMMUNICATION RS232:

The device sends information on the PV panel (Up) voltage and the PV panel (Ip) current, the battery voltage (Ub), and the battery current (Ib) to the DB9 terminal during operation. The data can be viewed with a Hyper terminal that works in Windows. The data output is as follows: Up=17.5V, Ip=2.5A Ub=13.2V, Ib=3.2A Setting of hyper terminal: baud=9600; parity=N; bits=8 (9600 8-N-1)
