Please keep this manual for future review.

This manual contains all instructions of safety, installation and operation for XTRA N series

Maximum Power Point Tracking (MPPT) controller ("the controller" as referred to in this manual).

General Safety Information

Read carefully all the instructions and warnings in the manual before installation.

No user serviceable components inside the controller. DO NOT disassemble or attempt to

repair the controller.

Mount the controller indoors. Avoid exposure the components and do not allow water to enter

1 General Information

1.1 Overview

XTRA N series controller which can carry different display units(XDB1/XDS1/XDS2) adopt the

advanced MPPT control algorithm, it can minimize the maximum power point loss rate and loss

time, quickly track the maximum power point(MPP) of the PV array and obtain the maximum energy

from solar array under any conditions; and it can increase the ratio of energy utilization in the solar

system by 20%-30% compared with PWM charging method.

Limiting the charging power & current and reducing charging power functions ensure the system

stable with over PV modules in high temperature environment. IP33 Ingress protection and isolated

RS485 design further improve the controller’s reliability and meet the different application

requirements.

XTRA N series controller owns self-adaptive three-stage charging mode based on digital control

circuit, which can effectively prolong the lifespan of battery and significantly improve the system

performance. It also has comprehensive electronic protection for overcharge, overdischarge, PV &

battery reverse polarity etc, to ensure the solar system more reliable and more durable. This

controller can be widely used for RV, household system, field monitoring and many other

applications.

2 Installation

2.1 Attentions

Please read the entire installation instructions to get familiar with the installation steps before

installation.

Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear

eye protection, and have fresh water available to wash and clean any contact with battery acid.

Keep the battery away from any metal objects, which may cause short circuit of the battery.

Explosive battery gases may come out from the battery during charging, so make sure

ventilation condition is good.

Ventilation is highly recommended if mounted in an enclosure. Never install the controller in a

sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and

destroy the controller circuits.

Loose power connections and corroded wires may result in high heat that can melt wire

insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use

cable clamps to secure cables and prevent them from swaying in mobile applications.

The controller can work with lead-acid battery and lithium battery within its control scope.

Battery connection may be wired to one battery or a bank of batteries. The following instructions

refer to a singular battery, but it is implied that the battery connection can be made to either one

battery or a group of batteries in a battery bank.

Multiple same models of controllers can be installed in parallel on the same battery bank to

achieve higher charging current. Each controller must have its own solar module(s).

Select the system cables according to 5A/mm2or less current density in accordance with Article

690 of the National Electrical Code, NFPA 70.

2.2 PV Array Requirements

(1) Serial connection (string) of PV modules

As the core component of solar system, controller could be suitable for various types of PV

modules and maximize converting solar energy into electrical energy. According to the open circuit

voltage (Voc) and the maximum power point voltage (VMpp) of the MPPT controller, the series

number of different types PV modules can be calculated. The below table is for reference only.
