- Page 4 1.MPPT Controller General Information 1 .1 Overview Controller based on multiphase synchronous rectification technology(MSRT)andadvanced MPPT control algorithm, has the features ofhigh response speed ,high reliability.and high industrial standard, MSRT can guarantee very high conversion efficiency in anycharge power, which sharply improves the energy efficiency ofsolar system. Advanced MPPTcontrol algorithm minimize the maximum power point loss rate and loss time, to ensure thetracking efficiency, corresponding speed as well as high conversion efficiency under high orlow power, so that in any situation, products can rapidly track the maximum power point(MPPof PV array to obtain the...

Page 6: Maximum Power Point Tracking Technology
1 .3 Maximum Power Point Tracking Technology Due to the nonlinear output of a solar panel or solar array, there is a maximum energy point(Max Power Point, or MPP) on the output curve at which the solar panel achieves its highestefficiency. Traditional solar charge controllers with switch charging PWM technology cannottrack this highest efficiency point of a solar panel, so most ofthe time they work with reducedefficiency and do not extract the full energy available from the solar panel. - Page 7 1 .4 Battery Charging Stage The controller have 3 stages charge mode, Constant Current Charging (Bulk Charging), Constant Voltage Charging (CV) and Floating Charging(CF) for rapid, efficient, and safebattery charging. a) Battery Changing Stage Curve In this stage, the battery voltage has not yet reached the constant voltage point (Equalize or BoostVoltage) and the controller operates in a constant current mode, delivering its maximum current tothe batteries (MPPT charging).

NOTE: The above parameter values are given under Standard Test Conditions (STC): irradiance 1000W/m2, Module Temperature 25°C, Air Mass 1.5.) 3 .3 PV Array Input Total Power This MPPT controller has a limiting function of charging current, the charging currentwill be limited within rated range.
- Page 11 3.4 Model of wires and breaker The installation ofinverter must strictly follow the local electrical requirements. The output current of solar panles will be effected by the model ofsolar panel cell, connection setting and the light intensity, so the minimum wire size is design according to the short circuit current of solar panels.
