DAILY MAINTENANCE CYCLE: When the solar panel starts delivering power (e.g. in the morning when the sun comes up) the OptiMate
Solar controller assesses the battery's charge level to decide the appropriate charge mode.
BATTERY CHARGED, MAINTAIN ONLY: If the battery is sufficiently charged, LED #4 or 5 will immediately light together with LED #1
(flashing).
BATTERY NEEDS CHARGE: If the battery needs further charging LED #2 or LED #3 will light together with LED #1 (flashing).
MULTI-STEP CHARGE MODE: The OptiMate Solar controller automatically alternates between pulse and continuous current mode
to always deliver the most efficient and fastest charge. The selected method of current delivery depends on
1) Condition of the battery – PULSE : Pulse mode is more effective in saving a battery.
2) Power delivered by solar panel –
a. PULSE: when the power is low (weak sun / cloud cover) pulses of effective charge current is delivered. Current pulses of 3
– 5 Amps may be delivered, at minimum every 2 seconds.
b. CONTINUOUS: when the power received from the panel is sufficient the controller delivers continuous charge current to the
battery during the BULK CHARGE mode (LED #3).
NOTES:
1.
Choosing the right size of solar panel: 12V solar panels are rated according to the maximum output it is able to deliver in direct
and full sunlight to a fixed 12V load. Maximum power is rarely achieved; output can drop below 20% in indirect sunlight (e.g.
cloud cover). For effective long-term battery maintenance choose a panel that will deliver sufficient current to overcome the
parasitic draw of the vehicle circuitry (such as alarm, clock, engine control unit) and return charge lost overnight. Typical parasitic
drain: 10-20mA for a motorcycle / power sport vehicle and 30-50mA for a car or pick-up truck fitted with a 12V battery.
2.
24-7 battery maintenance - The OptiMate SOLAR will maintain a battery whose basic condition is good, for months at a time. At
least once every two weeks,check that the connections between the charger and battery are secure, and, in the case of batteries
with filler caps on each cell, disconnect the battery from the charger, check the level of the electrolyte and if necessary, top up
the cells (with distilled water, NOT acid), then reconnect. When handling batteries or in their vicinity, always take care to
observe the SAFETY WARNINGS contained in this manual.

Description:
Battery save mode in progress - battery is deep discharged / voltage at connection was less
than 12V. Max. time: 2 hours
BULK CHARGE - maximum charge current up to 14.4V
OPTIMIZE - final charge is delivered for minimum 10 minutes. Charging may continue if the
battery requires further charging. Charge time is affected by strength of sun and size of
battery.
The battery is receiving maintenance charge up to a maximum voltage of 13.6V.
The battery is monitored, holding voltage between 13.3V and 13.6V.
