1.3 Accessories Instructions

1. Remote Temperature Sensor (Model: RTS300R47K3.81A)

Acquisition of battery temperature for undertaking temperature compensation of

control parameters, the standard length of the cable is 3m (length can be

customized). The RTS300R47K3.81A connects to the port (3th) on the

controller.

Note: Unplug the RTS, the temperature of battery will be set to a fixed value

25ºC.

2. Remote Meter (Model：MT50)

The digital remote meter displays system operating information, error

indications, parameters setting and self-diagnostics.

3. Super Parameter Programmer (Model: SPP-02)

The SPP-02 can realize one-key setting operation which is suitable for bulk

quantity products setting in the projects.

4. USB To RS-485 converter (Model: CC-USB-RS485-150U)

USB To RS-485 converter is used to monitor each controller on the network

using Solar Station PC software and update the firmware. The length of cable is

1.5m. The CC-USB-RS485-150U connects to the RS-485 Port on the controller.

1.4 Maximum Power Point Tracking Technology

Due to the nonlinear characteristics of solar array, there is a maximum energy

output point (Max Power Point) on its curve. Traditional controllers, with switch

charging technology and PWM charging technology, can’t charge the battery at

the maximum power point, so can’t harvest the maximum energy available from

PV array, but the solar charge controller with Maximum Power Point Tracking

(MPPT) Technology can lock on the point to harvest the maximum energy and

deliver it to the battery.

The MPPT algorithm of our company continuously compares and adjusts the

operating points to attempt to locate the maximum power point of the array. The

tracking process is fully automatic and does not need user adjustment.

As the Figure 1-2, the curve is also the characteristic curve of the array, the

MPPT technology will ‘boost’ the battery charge current through tracking the

MPP. Assuming 100% conversion efficiency of the solar system, in that way,

the following formula is established:

Input power (PPV)= Output power (PBat)

Input voltage (VMp) *input current (IPV) =Battery voltage (VBat) *battery current (IBat)

Normally, the VMp is always higher than VBat, Due to the principle of conservation

of energy, the IBat is always higher than IPV. The greater the discrepancy

between VMp &VBat, the greater the discrepancy between IPV& IBat. The greater

the discrepancy between array and battery, the bigger reduction of the

conversion efficiency of the system, thus the controller’s conversion efficiency

is particularly important in the PV system.

Figure 1-2 is the maximum power point curve, the shaded area is charging

range of traditional solar charge controller (PWM Charging Mode), it can

obviously diagnose that the MPPT mode can improve the usage of the solar

energy resource. According to our test, the MPPT controller can raise 20%-30%

efficiency compared to the PWM controller. (Value may be fluctuant due to the

influence of the ambient circumstance and energy loss.)

Figure 1-2 Maximum Power Point Curve

In actual application, as shading from cloud, tree and snow, the panel maybe

appear Multi-MPP, but in actually there is only one real Maximum Power Point.

As the below Figure 1-3 shows:

Figure 1-3 Mutil-MPP Curve

If the program works improperly after appearing Multi-MPP, the system will not

work on the real max power point, which may waste most solar energy

resources and seriously affect the normal operation of the system. The typical

MPPT algorithm, designed by our company, can track the real MPP quickly and

accurately, improve the utilization rate of the array and avoid the waste of

resources.

1.5 Battery Charging Stage

The controller has a 3 stages battery charging algorithm (Bulk Charging,

Constant Charging and Float Charging) for rapid, efficient, and safe battery

charging.

A) Bulk Charging

In this stage, the battery voltage has not yet reached constant voltage (Equalize

or Boost Voltage), the controller operates in constant current mode, delivering

its maximum current to the batteries (MPPT Charging).

B) Constant Charging

When the battery voltage reaches the constant voltage setpoint, the controller

will start to operate in constant charging mode, this process is no longer MPPT

charging, and in the meantime the charging current will drop gradually, the

process is not the MPPT charging. The Constant Charging has 2 stages,

equalize and boost. These two stages are not carried out constantly in a full

charge process to avoid too much gas precipitation or overheating of battery.

Figure 1-4 Battery changing stage Curve

Boost Charging

The Boost stage maintain 2 hours in default, user can adjust the constant time

and preset value of boost voltage according to demand.

The stage is used to prevent heating and excessive battery gassing.

Equalize Charging

WARNING: Explosive Risk!

Equalizing flooded battery would produce explosive gases, so

well ventilation of battery box is recommended.

CAUTION: Equipment damage!

Equalization may increase battery voltage to the level that

damages sensitive DC loads. Verify that all load allowable

input voltages are 11% greater than the equalizing charging set

point voltage.

CAUTION: Equipment damage!

Over-charging and excessive gas precipitation may damage the

battery plates and activate material shedding on them. Too high

an equalizing charge or for too long may cause damage.

Please carefully review the specific requirements of the battery

used in the system.

AVERTISSEMENT: Risque d’explosion!

l'égalisation de batteries noyées peut produire des gaz explosifs,

donc il est recommandé de bien ventiler le boitier de la batterie.

ATTENTION: Dégât sur l'équipement!

L'égalisation peut augmenter la tension de la batterie jusqu'à un

niveau nuisible pour les charges CC sensibles. Vérifiez que la

tension d'entrée autorisées de toutes les charges disponibles

sont supérieures à 11% à la tension du point d'installation de

chargement d'égalisation.

ATTENTION: Dégât sur l'équipement!

Un chargement excessif et une précipitation de gaz peut

endommager les plaques de la batterie et la formation de

matières actives dessus. Un chargement trop fort ou une

égalisation prolongée peut causer des dégâts. Inspectez

soigneusement les conditions spécifiques de la batterie utilisée

dans le système.
