www.sigineer.com 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.
www.sigineer.com 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.
www.sigineer.com 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.

www.sigineer.com Important: When using the Solar charger controller load control: Do not temperature-compensate these settings. Do not install the optional battery temperature compensation sensor. The follow accessories can be purchased for use with the Solar charger controller: Battery Temperature Sensor (BTS): The BTS is installed on the side of the battery and attaches to RS232 port inside the Solar charger controller.
www.sigineer.com The instructions that follow are applicable to the typical installation. For special applications, consult a qualified electrician or your Certified Dealer. Installation procedures will vary according to your specific application. Important: Installations should meet all local codes and standards. Installations of this equipment should only be performed by skilled personnel such as qualified electricians and Certified Renewable Energy (RE) System Installers.
www.sigineer.com The Solar charger controller is designed for indoor mounting. Care should be taken in selecting a location and when mounting the enclosure. Avoid mounting it in direct sunlight to prevent heating of the enclosure. The enclosure should be mounted vertically on a wall. In outdoor installations, the Solar charge controller must be installed in a rainproof enclosure to eliminate exposure to rain, mist or water-spray.
www.sigineer.com Before making any wiring connections to the Solar charge controller, it must be configured for the desired mode of operation. The following sections describe the how to configure the unit for the desired application and function. 2.4.1 Battery type selector can apply different charger method The battery type selector is a 10 position rotary switch used to set the Solar charger controller for the proper float and bulk voltage levels.
www.sigineer.com Provides an additional Float and Bulk settings for deep cycle, lead acid Deep Cell 13.3 26.6 batteries. Refer to the Lead Acid 2 battery manufacturer recommendation for Float and Bulk settings. Provides an additional Not Specified 13.6 14.3 27.2 28.6 setting of Bulk and Float voltages.
www.sigineer.com 2.5.1 Temperature compensation based on battery type The charge voltage required by batteries changes with battery temperature. Temperature compensation of charge voltage enhances battery performance and life, and decreases battery maintenance. Automatic temperature compensation can be provided through use of the optional battery temperature sensor. The following table describes approximately how much the voltage may vary depending on the temperature of the batteries.

Once the wires have been installed, torque the terminals as follows. Be careful not to over tighten. Figure 1 – 8: DC terminal connector locations Load Negative (-) PV Negative (-) Load Positive (+)
www.sigineer.com 2.8.2 Surge Protection Since PV arrays are often mounted on an elevated structure and thus are more susceptible to lightning strikes, protection from lightning-induced power surges and other transient power disturbances between the PV array and the Solar charge controller are strongly recommended. Because the Solar charger controller have wider input voltage range 15-55VDC.

www.sigineer.com Batteries come in different sizes, types, amp-hour capacity, voltages and chemistries. Here are a few guidelines that will help in battery selection, and ensure that the batteries are properly maintained. The best source of the most appropriate settings for the Solar charger controller will be from the manufacturer or supplier of the batteries.
www.sigineer.com hardens, the sulfate is removed from the plates. Batteries with liquid electrolyte may become stratified. Stratification concentrates the sulfuric acid into the bottom of the cell while the top becomes diluted. This corrodes the lower portion of the plates, reducing battery life. Mixing of the electrolyte by the formation of gas bubbles during the equalization process reduces stratification.
