Grilled whole chicken, also known as "Lechon
manok," is the product of small stalls in the Philippines
and is one of the businesses that use charcoal as their
primary heat source for roasting chicken. Energy
deficiency is one of the primary concerns that affect
businesses resulting in unproductive service. Lechon
manok stalls are one of these dominant businesses in the
Philippines. Converting the waste heat produced by the
stall into electricity is possible using a thermoelectric
generator. It converts heat energy into electrical energy
through the Seebeck effect of supporting the stalls'
electricity needs. Placing these modules at the top of the
machine harvests waste-heat energy by radiation,
convection, and conduction. By series and parallel
connection of the modules, its output power will increase.
Relays were used to switch the flow of current from the
battery in the system. Two cells are used for the charging
and discharging state. The output node of the modules is
connected to a relay, charging batteries with low-level
