Page 15: Mounting The Eqx 500-Dc Solar Chargercontroller
The EQX 500-DC solar charger charge 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 EQX 500-DC solar charger charge controller must be installed in a rainproof enclosure to eliminate exposure to rain, mist or water-spray. -

Page 18: Temperature Compensation Based On Battery Type
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. -
Page 19: Grounding
2.8.1 Current Rating EQX 500-DC solar charger charge controller is rated for a rating continuous current of 40 amps. Since PV outputs can vary due to the array size or sunlight striking it, the safe minimum wire size should be based on the maximum current ratings. -

Page 25: Operation
Single color LED indicator Multicolor LED indicator The EQX 500-DC solar charger has one multicolor LED and one green LED to indicate the operating status of the controller. The green LED indicates whether the charging source is functioning properly when it display solid green or the type of the fault when it flash. -
Page 26: Table 1 - 6: The Led Indicators
If the EQX 500-DC solar charger connected with DC load, the load is disconnected before the transistors reach an excessive temperature and the green LED flashes. -
Page 27: Troubleshooting
PV- & BAT- must be separate for proper operation. PV- must receive earth ground via shunts inside the EQX 500-DC solar charger which internally connect PV- to BAT-. External connection prevents proper operation of internal shunts and current measurement system. -

Page 31: Batteries
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 EQX 500-DC solar charger charge will be from the manufacturer or supplier of the batteries. -
Page 32: Equalization Charging
Approximately every month, some batteries may need to be “equalized.” Since the individual cells of the battery are not identical, some cells may not be fully charged when the charging process is completed. If the batteries have been left in a discharged condition for long periods of time, the plates will have sulfates on them from the electrolyte.
