INTRODUCTION

The present manual sets out safety standards, installation process and settings of the device and related system components. This manual is for use by any

qualied personnel who plan to install the device and related system components. Some connection and setting work should be carried out by qualied

personnel only in cooperation with local energy supplier or authorized dealer. We strongly recommend the installation, commissioning, maintenance and

repair carried out by well qualied personnel only.

GENERAL DESCRIPTION AND FEATURES

The solar controller SEC is a MPPT controller (hereinafter referred to as the "controller") of the Accumulator battery charge (hereinafter referred to as "AB")

from the solar panels array (hereinafter referred to as "SP"), with the tracking of the maximum power point (MPPT). This product has many important advan-

tages, namely:

Eciency up to 98% allows not only to collect all solar energy practically without losses, but also makes it possible to avoid using cooling fans: it signicant-

ly increases the reliability of device.

High performance, and therefore up to 10% higher eciency (compared to some 3rd party MPRT controllers) and up to 40% compared

to PWM controllers.

The allowable input voltage limit of the controller is 200 V (or 250 V - depending on the modication), therefore the array of solar panels may consist of up

to 3 (or 4) solar panels with 24 V rate, connected in series (open circuit voltage of each one - without load - can reach 45 V at temperature + 25C°, which is in

total 3 * 45 = 135 V, or 4 * 45 = 180 V).

Two current Hall Eect sensors (which is much better than a shunt) for monitoring of charging/discharging by other device (for example, by a wind turbine

and/or from an inverter) - are optional.

The current sensors make possible to cooperate with a hybrid inverter onto the AC grid of 220 V: it allows to add current instantly in AB bypass. It may be

even greater than AB allowed charge current; anyway, the use of AB with a minimum capacity is necessary. It concerns any ordinary inverter: power addition

to the load by use of SP without AB charge wasting. This option is very important as the energy can go“in transit”. AB are not wasted, and therefore, they serve

much longer.

Own transformer-based power supply from the SP allows to feed the controller regardless the battery state. Operation is possible even with fully discharged

battery, at a minimum voltage.

Counter of incoming A*h / W*h.

Ability to update the rmware in the ash-memory.

The controller allows to set manually any non-standard voltage for working with AB (besides 12/24/48/96V). It is useful for non-standard alkaline batteries,

or batteries with a non-standard number of cells.

Peak current (up to 100A or 60A depending on the modication) and the ability to operate in 96V systems, allows to obtain the peak power from one

controller: up to 11kW (current 100A is multiplied by the AB buer voltage 110V).

TECHNICAL SPECIFICATIONS

The possibility to connect lithium-iron-phosphate (LiFePO) batteries with BMS. The controller manages BMS or, if necessary, automatically transfers the

control to the MAC inverter (the controller is connected by additional cable to MAC, and MAC can control the BMS).

Three programmable powerful relays for external devices control: for example, in complete autonomy, it is possible to turn othe refrigerator automatically

for the night by keeping more ice or cold accumulator in the freezer for energy saving. Unlike competitors, SEC DOMINATOR and PRO have the powerful relay

of 3.5kW - 240V 16A (i.e. it is possible to connect, for example, a refrigerator, directly through the controller, without any supplementary relays). Temperature

compensation and charging mode correction extend the battery life.

Three stage buer charge.

Tropicalized construction: the controller board is protected by a waterproof coating (varnish), which minimizes the harmful eect of a high humidity and

insects.

Possibility of remote monitoring with“MALINA”Appliance.

The controller also can be used to charge battery from wind turbine.

The controller allows you to update its ash-memory rmware. Details are given in Appendix 3.

The main dierence between version 6.0 and previous versions is the modication in the control interface and indication algorithms.

ATTENTION! This manual is valid for rmware version 6.0 and higher. If you are using a device with an earlier rmware version, we recom-

mend you update it to the latest or use earlier versions of the user manual.

IMPORTANT SAFETY INSTRUCTIONS.

STUDY, SAVE AND STRICTLY FOLLOW!

This sign is used together with a warning notice "Danger" or "Warning", or instead of it and means that violation of the requirements may cause

an electric shock.

This is a sign of warning. It is used to draw an attention to the potential danger of personal injury or essential property damage. Follow all the require-

ments listed after this sign. Violation of the requirements may cause a damage to equipment and injury or death.

ATTENTION! Dangerous voltages are possible in the system!

The installation and all connections should be done by well qualied personnel only.

ATTENTION! If the controller is connected to both the solar panels (SP) and AB (especially when the charge with SP is going on) it is

forbidden to disconnect the controller from the AB. This can lead to the controller damage, which is not covered by warranty. For the

same reason, it is forbidden to install a circuit breaker between the controller and the battery or, if necessary, it must have a large

current reserve relative to the controller current (at least 150% of the controller's maximum current).

SAFETY REQUIREMENTS:

1. Before using the controller please study all the instructions and warning labels on your device and batteries, as well as all the relevant chapters

of this manual.

2. The use of accessories which are not recommended or not supplied by the manufacturer may cause a risk of re, electric shock or injury.

3. Make sure that existing wiring is in a good condition and has a proper sectional area to avoid the risk of re and electric shock. Do not connect the controller

to a damaged or defective wiring, as well as defective electrical equipment.

4. In the case of any failure of the inverter please don't use it.

5. This device contains no user serviceable parts. Do not disassemble the inverter, except when it is directly mentioned for wire and/or cables connection. Inside

repair may cause a risk of electric shock or re. Internal capacitors remain charged after power is switched ocompletely.

6. Before maintenance, cleaning or working with any components connected to the controller please disconnect the inverter from AC and DC sources to reduce

the risk of electrical shock. Standby mode of the device does not reduce the risk.

7. The device must be protected from rain, snow or any liquids. Operating in a humid environment shorten the product lifetime. The warranty does not cover

the corrosion caused by high humidity.

8. To avoid the risk of short-circuit use always the tools with insulated handles while installing or working with this equipment.

9. When working with electrical equipment please take ometal items, such as rings, bracelets, necklaces, watches, etc.

10. It is necessary to observe polarity of the AB strictly when attaching to the controller. Incorrect connection leads to controller damage. In this case the repair-

ing will not be covered by warranty.

11. It is necessary to observe the temperature conditions and humidity during operating.

12. Do not place the controller in dusty environments.

13. It is not allowed to use the converter for other purposes, the same as to exceed the recommended operating parameters.

14. If AB are not sealed, they should be placed in a ventilated room.

15. It is necessary to prevent the access of children, animals and unskilled personnel to the controller and battery.

When choosing a controller placement, it is necessary to follow the re safety regulations and electrical equipment and accumulator batteries

operating rules.

The controller must be installed in a dry and well-ventilated place. The controller should be placed as close to AB as possible and connected by conductors of

the required sectional area. The conductors must withstand the expected charging current of your system. It is not recommended to make AB connection

conductors more than 3 m long to avoid a large voltage loss. When longer cables are required it is necessary to increase their sectional area by 2-3 times.

It is necessary to install the temperature sensor on one of the AB sides and x it securely.

Watch this restriction especially when installing the system in places where high solar radiation and low temperatures may occur. Approximately, the voltage

of the open SP circuit increases by 20-25% at -30°C, i.e. the solar panel with 45 V open circuit voltage at + 25°C, will generate 55V at -30°C.

The required sectional area of SP conductors depends on the array capacity and its voltage. The best eciency is achieved when the input voltage

of the controller is twice the battery voltage.

The controller is wall-mounted. Installation should be done on a vertical surface (wall) with free space of at least 15 cm from the sides and at least 25 cm from

the top. Otherwise, the controller may become overheated, what reduces the generated power.

To mount the product please x 4 screws of proper size in the wall according to the drawings and x the product on them.

CONTROLLER PLACEMENT AND INSTALLATION

ATTENTION! The input voltage of the controller connected to the solar panels array should never exceed 220V/250V (depends on model).

The controller can be damaged by input voltage surplus which is not covered by warranty.

For the cables connecting please remove the bottom cover by unscrewing the 4 screws at the bottom of the body, cut the required size holes through the

rubber gaskets, pass the cables through them and put the cover back. The description of the connectors and the recommended wiring diagrams are given

Modes and operational parameters are displayed by the LCD and 3 LEDs:

“SOURCE” (Blue LED) – indicates the input voltage level (the state of SP). If the SP voltage exceeds AB voltage for more than 5V then the LED is constantly on.

When the dierence is more than 1-5V - then the LED is blinking. But when SP voltage is below AB voltage plus 1V then the LED is OFF.

“CHARGE” ((Green LED) – indicates AB charge mode. For cyclic charge (charge by maximum current) the LED is constantly ON.

In absorption charging mode the LED blinks evenly.

In the modes of equalization and charge maintaining the LED blinks seldom.

“Battery” (Red/Green LED) – indicates AB charge level.

The LED changes its color in 2-second period. The higher AB charge is the longer the LED is green and the remainder of period (the rest from 2s) it is red.

Thus, when AB is fully charged the LED is constantly green; if AB is half charged then the light is green/red changing one after another; for discharged AB the

light is constantly red.

LCD display has 2 rows of 16 characters each and is served for displaying the current parameters and user settings input.
