Page 4: Important Safety Information
• Disconnect all sources of power to the controller before installing or adjusting the MPPT. • There are no fuses or disconnects inside the MPPT. Do not attempt to repair it. • Install external fuses/breakers as required. -
Page 5: General Information
Please take the time to read this operator’s manual and be familiar with the controller. This will help you make full use of the many advantages the MPPT can provide for your PV system. - Page 6 1 - Battery Status LED Indicator An LED indicator that shows battery status or system errors. 2 - Charging Status LED Insdicator An LED indicator that shows charging status and overvoltage of pv. 3 - Setting Button1 Set load work mode,battery type and max charge current. 4 - Setting Button2 Set load work mode,battery type and max charge current(in manual mode used for load ON/OFF).

Page 7: Installation
If required, the controller may be in- stalled in a ventilated enclosure with sufficient air flow. Never install the MPPT unit in a sealed enclosure. The controller may be mounted in an enclosure with sealed batteries, but never with vented/ MPPT circuits. - Page 8 1. Attach the mounting hanger to the bottom of the MPPT with the M6 screw provided as shown in figure 3-1. 2. Place the MPPT on a vertical surface protected from direct sunlight, high temperatures, and water. The MPPT requires at least 150 mm of clearance right and left.

44 Amps of charge current flowing out to the battery.The MPPT does not create current! Rest assured that the power into the MPPT is the same as the power out of the MPPT. Since power is the product of voltage and current (Volts x Amps), the... - Page 13 In this situation, there will be very little or no MPPT gain compared to traditional controllers. However, systems with modules of higher nominal voltage than the battery bank will always have an array V greater than battery voltage.

Equalize Stage WARNING: Risk of Explosion Equalizing vented batteries produces explosive gases. The battery bank must be properly ventilated. CAUTION: Equipment Damage Equalization increases the battery voltage to levels that may damage sensitive DC loads. Verify all system loads are rated for the temperature compensated Equalize voltage before beginning an Equalization charge. -
