3.3.3

Programming field 2 : Select special mode

BOOST and REFRESH modes are idle by default on the solar charge controller because the solar power source is not
permanent and therefore the MPPT may not complete full battery recharge cycles; which can affect their lifespan. A
solar source is a back-up source, which helps compensate for small battery discharges. The user can, if he likes,
reactivate these modes.
- The BOOST function allows a faster charging of the batteries. This function is timed in time (see section
3.3.2.) And is automatically inhibited if the battery is charged: shutdown of the BOOST for a battery
current <20% of the nominal current of the MPPT (2A in the case of the Lithium curve Iron Phosphate
with BMS with a minimum time of 10 minutes).
- The REFRESH function allows to apply a voltage step periodically to maintain the battery, to promote
its equalization and thus prevent possible sulfating.
