SAFETY PRECAUTIONS:

1.Make sure your battery has enough voltage to register on the charge controller (8V DC minimum).

2.Make sure you have the right size wire. Wire sizing typically includes 2 considerations:

A. NEC minimum wire size to avoid overheating the wire, based on insulation material.

The following is an excerpt from the National Electrical Code . It can be used as a general guideline for wire sizes. Take note of the materials listed (copper/aluminum) and temperature rating. Many of Cutting Edge Power’s wire is not included in this table because we use very special, high temperature/current rat- ed 200°C silicone insulated tinned copper wire.

B. Voltage drop, to avoid low voltage / high current issues.

Voltage drop is a phenomenon that can affect low voltage (under 60V) systems quite a bit. We recommend checking with the voltage drop calculator from calculator.net found here. One of the biggest problems with having a voltage drop too low, is that it proportionally increases the current of the system, which can have a tendency to overheat wiring or components. You can read more about this on our blog. As a general rule of thumb, 2% voltage drop is considered good, and 3% voltage drop is considered acceptable.

When in doubt, bigger wire is better.

Note: the largest practical size wire that can be used in this charge controller’s terminals is 10AWG. 10AWG silicone insulated tinned copper wire is rated for 140.6A maximum.

3.This charge controller is suitable for charging lead acid 13.7V nominal batteries (deep cycle, AGM, Gel, SLA) as well as Lithium Iron Phosphate (LiFePO4) 4S 12.8V nominal batteries.

It can be used to charge Nickel Oxide based lithium batteries, but it isn't recommended because you won’t be able to use the full voltage range of these batteries.

How does it work?

MPPT is a fascinating technology. MPPT stands for Maximum power point tracking. Basically, it is a charging control technique that determines the point at which a solar panel’s maximum voltage and current (thus, power) can be used to charge your battery. A visual graph of a typical solar panel is shown below. The line which follows the “knee” of the curves indicates the maximum power point. As you can see, the maximum power point will change depending on the amount of sunlight. The ability of this charge controller to adapt and harvest the maximum amount of power with any given amount of sunlight is what makes it almost 99% efficient. You can read more about MPPT here.

DON’T BELIEVE US??

Perform your own precise tests using our Smart Tech Power Meter. Designed specifically for wind and solar, our Smart Tech Power Meter is perfect for all of your testing needs. Easy pairing through your standard WiFi router or phone's hotspot, you can view the measured voltage, current (amps) and the power output (Watts).

CONNECTIONS:

1.Always connect the battery first, then solar panels. This is to prevent a voltage surge or spike from damaging the sensitive electronics in the charge controller.

2.Connect the solar panels second.

23V maximum solar panel Open Circuit Voltage (VOC) input for charging 12V battery/batteries. 46V DC maximum solar panel Open Circuit Voltage input (VOC) for charging 24V batteries.

See “Specifications” for more details.

3.If applicable, connect “load” last.

4.Reversing the polarity will result in a damaged charge controller and will void the warranty.

BUTTON GUIDE:

Menu button: short press to scroll through settings. Long press to modify settings.

Up button: Short and long press does nothing from home screen. Use to adjust settings after long pressing the menu button.

Down button: Short press turns on/off the “load” output. Use to adjust settings after long pressing the menu button.

Long press at home screen to engage or disengage the “load” function.

“LOAD” OUTPUT FUNCTION:

The load function is typically used for lighting applications, hence the light bulb icon. It can commonly be set to turn on a load output after dusk (when the charge controller detects 8V or less, it assumes it’s night time). The time aspect (24h, 1-15h, 0h) is the time the load output will remain engaged. After this time is elapsed, the load output will be disengaged.

Important: The load voltage settings and time settings must be satisfied in order for the load output to engage.

SCREEN GUIDE:

Settings that are adjusted will be automatically saved, even if power is removed.

Home Screen:

Default display which shows the battery voltage, if the solar panels are charging, and if the load output is engaged.

From the home screen, short press “menu” to view the status of all parameters.

When you get to a setting you want to change, long press “menu” for 3 seconds to enter “edit mode”. After the setting is adjusted, to save: short press “menu” or just wait for the screen to time out.

PV OFF:

The voltage at which solar charging will be disconnected. PV OFF should be the maximum voltage you want your battery/batteries to be charged. (Typ.

Note: this MUST be modified for LiFePO4 batteries!! Refer to your battery speci- fications!

LOAD ON (Voltage):

The voltage at which the load output will be engaged (if allowed by time setting).

LOAD OFF:

The voltage at which the load output will be disconnected. This is a protective setting to prevent the battery from overdischarging.

LOAD ON (Time):

The time at which the load output can be engaged. 24h means the load will al- ways be on as long as the voltage doesn't drop below “LOAD OFF”. 1-15h means the load output will be engaged for this many hours after the charge controller no longer detects the solar panel (sunset). 0h activates the “dusk to dawn” setting; load will be set to engage at dusk and disengage at dawn.
