Sundaya Apple User Manual

Apple
The "Apple" is a unique small PV charge/discharge in Sundaya product range specially designed for very low
cost applications based on SMD technology. The Apple is extremely power efficient due to it very low voltage drop
over both input and output switching Mosfets, and a buzzer to indicate that user is close to LVD (Low Voltage
Disconnect). The Apple also has an electronic master-switch or On/Off-switch, and a clear state of charge indicator that
also gives u a good indication during charging.
Frequent cycling of the battery at a very low state of charge causes fast deterioration of the battery due to
sulfation and stratification. The Apple does not allow the user to frequently operate the battery at low state of
charge.
The Apple is available in 3 standard charge/discharge current capacities; 5, 10 and 15 Amperes. It's clean and
round appearance make the product look nice on your wall; with all cable connections nicely covered at the
backside of the unit.
Main Features:
Strong input and output connectors with clear polarity marking
Cable connectors not reachable and not visible after mounting on the wall (safety and esthetic reasons)
Extremely low voltage drop over power mosfets
Boost Charge mode
LED Indicator for charging
LED Indicator for state of charge in 8 steps
