Solar charger controller is a 40/60 amp 12/24/48 voltage Maximum Power Point Tracking (MPPT) photovoltaic

(PV) battery charge controller. Through the use of MPPT technology, Solar charger controller can increase charge

current up to 30% or more compared to conventional controllers. Solar charger controller’s sophisticated three

stage charge control system can be configured to optimize charge parameters to precise battery requirements. The

unit is fully protected against voltage transients, over temperature, over current, reverse battery and reverse PV

connections. An automatic current limit feature allows use of the full 40 amp capability without worrying about

overload from excessive current, voltage or amp-hour based load control.

Series pass Pulse Width Modulation (PWM) charge voltage control combined with a multistage charge control

algorithm leads to superior charging and enhanced battery performance. The filtered PWM power control system

uses highly efficient and reliable power MOSFET transistors. The MOSFET’s are turned on and off at high

frequency to precisely control charge voltage and MPPT.

Fully automatic temperature compensation of charge voltage is available to further improve charge control and

battery performance. The optional battery temperature sensor is built for long term reliability. The sensor element

is environmentally sealed and encapsulated into a plastic lug which adheres to directly to the battery terminal and

by RJ11 port connect with the unit, And the Solar charger controller also includes an isolated RS232 port for

connection to a PC computer for data logging and system monitoring.

The Solar charger controller can easily install in parallel connection of output, so it also suitable for large system

current application condition.

Very cold batteries combined with high charge voltage setpoints can produce voltages high enough to disrupt or

damage other equipment connected to the battery. To minimize possible damage a maximum voltage setpoint limit

feature is provided. The factory defaults can be adjustable using software. Regardless of what setpoint values

result from temperature compensation, the Solar charger controller will never attempt to apply a charge voltage

greater than the maximum voltage setpoint limit value.

Over temperature protection is provided to protect the unit from damage due to high output power at high ambient

temperatures. When mounted vertically as described in the installation section, the unit can deliver full output in a

temperature of up to 40℃, and the unit will de-rate output in 40 - 60℃. While operating in charge mode, the

controller will decrease the charge current to reduce the transistor temperature and the green led will be blinking

green. reducing average power delivery to within safe limits. During thermal shutdown the charge status indicator

will display an “off” condition. Over temperature shutdown occurs when the ambient temperature reaches 60℃.

MPPT and associated current boost operation is fully automatic and will function whenever sufficient PV voltage

and current are available. The percent increase in output charge current relative to PV current is variable, and will

change with operating conditions. When conditions are such that insufficient PV power is available to produce an

increase in output current, the unit will stop it’s internal DC-DC power conversion and operate as a series pass

PWM controller with very low forward voltage drop.

The principal operating conditions which affect current boost performance are PV array temperature and battery

voltage. At constant solar intensity available PV power changes with PV temperature. A PV array’s power vs.

temperature characteristic is such that a cool PV array can produce a higher voltage and more power, than a hot

PV array. When PV voltage is sufficiently high for MPPT to operate, a constant power output is delivered to the

battery. Since output power is constant while MPPT is operating, a decrease in battery voltage produces

corresponding increase in charge current. This means that the greatest current increase occurs with a combination

of cool ambient temperature and low battery voltage. The unit delivers the greatest charge current increase when

you need it most, in cold weather with a discharged battery. Additionally, anything that can be done to lower PV

array temperature will also lead to increased charge current by increasing PV power production. In

cool/comfortable temperatures and typical battery states of charge, most systems see about 10 –20% increase.

Charge current increase can go to zero in hot temperatures, whereas charge current increase can easily exceed

30% with a discharged battery and freezing temperatures.

A PV module is a constant current type device. As shown on a typical PV module voltage vs. current curve,

current remains relatively constant over a wide range of voltage. A typical 75 watt module is specified to deliver

4.45 amps @ 17 volts @ 25 C cell temperature. Conventional PV controllers essentially connect the PV array

directly to the battery when battery is discharged. When a 75 watt module is connected directly to a battery

charging at 12 volts, the module still provides approximately the same current. But, because output voltage is now

at 12 volts rather than 17 volts, module power production is artificially limited and the 75W module only delivers

53 watts. This wastes 22 watts of available power.

Solar charger controller’s MPPT technology operates in a very different fashion. Under these conditions Solar

charger controller calculates the maximum power voltage (V) at which the PV module delivers maximum power,

in this case 17 volts. It then MPPT operates the module 17 volts which extracts maximum available power from

the module. Solar charger controller continually recalculates the maximum power voltage as operating conditions

change. Input power from the maximum power tracking controller, in this case 75 watts, feeds a switching type

power converter which reduces the 17 volt input to battery voltage at the output. The full 75 watts which is now

being delivered at 12 volts would produce a current of 6.25 amps. A charge current increase of 1.8 amps or 40% is

achieved by converting the 22 watts that would have been wasted into useable charge current. Note that this

example assumes 100% efficiency to illustrate the principal of operation. In actual operation, boost will be

somewhat less.

Solar charger controller is fully protected against reverse polarity and high voltage transients for both the PV and

the battery connections. If the battery is connected reverse polarity, Solar charger controller will be protected by

inner fuse and fuse will be open. If the PV array is connected reverse polarity the charge control system will not

turn on.

All electronic circuits may be damaged by static electricity. To minimize the likelihood of electrostatic damage,

discharge yourself by touching a water faucet or other electrical ground prior to handling the unit and avoid

touching components on the circuit boards. The risk of electrostatic damage is highest when relative humidity is

below 40%.

Solar charger controller is typically configured for a three stage charging process, Bulk, Absorption and Float. The

three stage charge process provides a somewhat higher charge voltage to charge the battery quickly and safely.

Once the battery is fully charged a somewhat lower voltage is applied maintain the battery in a fully charged state

without excessive water loss. The three stage charge process charges the battery as quickly as possible while

minimizing battery water loss and maintenance.

Figure 1 –1: Bulk charge curve

1.10.1 Bulk charge

When charge starts the Solar charger controller attempts to apply the bulk charge voltage to the battery. The

system will switch to Bulk charge if the battery is sufficiently discharged and/or insufficient charge current is

available to drive the battery up to the bulk voltage setpoint. During the Bulk charge stage the unit delivers as

much charge current as possible to rapidly recharge the battery. Once the charge control system enters Absorption

or Float, the unit will again switch to Bulk charge if battery voltage drops below the present charge voltage
