2. PRODUCT INTRODUCTION 2. PRODUCT INTRODUCTION -2.5 Charging Stages Introduction Compared with conventional PWM controllers, the MPPT controller can make the most of the solar panel's max. power and therefore provide larger charging current. Generally speaking, the latter can raise the energy utilization ratio by 15% to 20% in contrast with the former. As one of the charging stages, MPPT can not be used alone, but has to be used together with boost charging, floating charging, equalizing charging, etc.
3. PRODUCT INSTALLATION 3. PRODUCT INSTALLATION -3.2 Wiring Specifications > Equalizing charging Wiring and installation methods must comply with national and local electrical specifications. The wiring specifications of the battery and loads must be selected according to rated currents, and see the following table for wiring specifications: Warning: risk of explosion! In equalizing charging, an open lead-acid battery can produce explosive gas, therefore the battery chamber shall have good Battery wire...
