General description
ESUN PLUS BOOST is a photovoltaic charge controller for leaden electrochemical batteries either sealed (SEAL) or
flooded lead acid (FLOOD) or lithium ions or LiFePO
4
. In
Pic.1
there is a scheme principle of ESUN PLUS BOOST. It is
absolutely forbidden connect to ESUN PLUS BOOST lithium-ion batteries without a BMS; the BMS protect the battery
from unsafe operating condition that can to lead battery to explosion or to burn up.
Pic.1 Principle diagram
1- Charge circuit: it adapts Vpan and Ipan (respectively voltage and current of the PV module) so to search the
condition in which the power that is given by the PV module is maximum, thus realizing the MPPT (
Maximum Power
Point Tracking
). In addition, it manages the battery charge by reducing the current sent towards the battery when
the battery Vbatt exceeds its charge voltage (Veoc).
2- Circuit for load control: it turns on/off the load according to the program set by the user and it provides to load
detachment in case of discharged battery, overload or short-circuit on the load.
3- Microprocessor: it controls the whole circuit, it measures currents and voltages of PV module, battery and load and it
shows them on the display.
