This charger is designed for indoor use only and should never be exposed to rain.
Do not disassemble the controller. Contact Zamp Solar support if the unit requires attention.
Lead acid, LCO, LiFePO4, LTO, LI-95 batteries can be dangerous. Ensure no sparks or flames are
present when working near batteries.
Eye protection should always be used. Never short circuit the battery.
Given sufficient light solar panels always generate energy even when they are disconnected.
Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a
fire hazard. We recommend that you cover up the panel(s) with cloth or cardboard so you can
block all incoming light during the installation. This will ensure that no damage is caused to the
Solar Panel or Battery if the wires are accidentally short circuited.
Always install a battery fuse on each circuit including the solar controller
Do not reverse connect the wires to the solar panel or battery

To protect the Battery and the Solar Panel, it is strongly recommend that you place an inline fuse
on the positive wire on both the “Solar” and “Battery” Circuits. 40A fuse for 30A controller, (As close
to the Battery /Panel as possible)

Refer to the below drawing, please cover the solar panel before connecting cables.
CORRECT WIRE SIZE:
Please refer to the wire size chart below to determine the minimum size wire needed for each
connection. This will also ensure you get the best performance out of your solar controller.
It is recommended to install the solar charge controller as close to the battery as possible.

TECH SUPPORT 541-728-0924 [e-mail]

This solar controller provides multiple charging stages with smart charging algorithm.

For Lead acid battery (Crystal, Gel, AGM, WET and Calcium battery):
Soft Charge – Bulk Charge - Absorption charge - Equalizing Charge* - Float charge
For Lithium battery (LCO, LI-95, LFP, LTO battery)
Soft Charge – Bulk Charge - Absorption charge – Stop and Restart charge*
Soft start - When batteries suffer an over-discharge, the controller will softly ramp the battery
voltage up to 10V.
Bulk Charge - Maximum current charging until batteries rise to Absorption level. For Lead crystal
battery type, the charge controller will deliver two step level of Bulk charge, when the first level
rises the battery voltage up to 14.4V, then switch into the second level of the 10% of the first bulk
charge rate, until the Lead crystal battery voltage up to 14.7V.
Absorption - Constant voltage charging and battery is over 85% for lead acid battery; the Lithium
battery (LCO, LFP and LTO battery) will close fully charged after absorption stage, for LI-95 Lithium
battery will be charged 95% Capacity.
Equalization * - Only for WET or Calcium battery type, when the battery is deeply drained below
10V or every 28 days cycle, it will automatically run this stage to bring the internal cells as an equal
state and fully complement the loss of capacity. (Lead crystal, Gel, AGM battery or Lithium
batteries do not run Equalization charge)

Float Charge or Re-Start charge* - Battery is fully charged and maintained at a safe level.
A fully charged Lead acid battery (Crystal, GEL, AGM, WET or Calcium battery) has a voltage of
more than 13.6 Volts; if the lead acid battery voltage drops to 12.7V at float mode, it will return to
Bulk charge, Lithium battery will stop charge after Absorption stage, it will restart to bulk charge if
the voltage discharge less than 12.0V for LCO battery, 13.0V for LTO battery, 13.3V for LFP or LI-95
battery.
Remarks - This controller provides an override function (force output delivery) for some heavily
discharged Lead acid batteries (Low to 0V), or for some LiFePO4 batteries which are protected by
BMS due to over-discharged. Press BATT / - button for 3 seconds to wake up the Lithium battery
(activate the BMS against protection) or override the Lead acid battery.

– Reverse polarity solar and battery connection.
– Against reverse current from battery to solar panel at night.
– Transient over voltage protection, a varistor or transient voltage suppressor (TVS) at the solar
input and battery output against surge voltage.
Remarks: Battery Voltage settings for 12V mode, x2 for 24V mode. *The LI95 battery profile
keeps your LiFePO4 battery charged at 95%. Evidence suggests that charging your Lithium
battery to less than 100% can increase longevity of your battery.
Occasionally check that the wire terminals are securely tightened. Inspect wiring to ensure
nothing is or has become exposed. Repair if necessary.
Occasionally, clean the case using a damp cloth and mild cleaning agent.
