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.
