_MPPT- Solar Boost Controller -550W- Instruction Manual _
I. Safety Recommendations Ruan Wei Wu Wei Peng
1 The battery pack stores a large amount of energy. When using it under any circumstances, be sure not to short-circuit the battery pack. We recommend that the controller be equipped with a fuse (smart action type, select according to the rated current of the controller). ′` -
2. The battery pack can produce flammable gas. Keep away from fire sources, ensure that the battery pack is stored in a ventilated place, and do not short-circuit wires and terminals, because some terminals or wires can generate up to twice the rated voltage and current of the battery pack. When operating, you need to use insulating tools. 3. Please keep children away from the battery pack and controller. 4. Please follow the safety recommendations of the battery pack manufacturer. ' f l 「
5. When installing this controller, it is best not to install the controller directly on the metal bracket.
II. Scope of application' ˇ | National Garden
1. This controller is only suitable for solar panels with 12v to 5ov input and boost output charging voltage. 24V to 88Vy battery pack. Use sheath group brother epidemic person one one one one
sealed milling acid battery pack and lithium iron phosphate battery or lithium battery one′ n book cut
III. Product function! 「 1. MPPT maximum power tracking boost charger, maximum MPPT efficiency 98%, 2. The system power supply adopts solar panels to supply power, and the rest is 1.18V, 1.2A, 1.4A ... Lithium iron phosphate battery, ternary lithium battery, porcelain group charging sequence ˇ
5. System abnormality, one-key reset and restart. | _ '二l熙i二壹损熙壹…夏茫言量壹$牡′…黄′…

8 Use 0LED display to display photovoltaic panel voltage, current, power, as well as display charging voltage and controller working temperature〕
. When the temperature exceeds 38[C, the fan is intelligently turned on for heat dissipation, and the low When the temperature reaches 38"C, the fan will be intelligently turned off to reduce power consumption and improve efficiency.
IV. System Operation ˇ Zhang - Garden Project
After the system is connected normally, if there is a sun, the system starts to start. When it starts, the 0LED display lights up and the system starts. -
After the system is started, the 0LED display lights up, showing the voltage, current, power and power generation of the photovoltaic panel. When the charging current shows 0.04, charging is completed and charging stops. Note: Please do not exceed the working range.

At night, when the photovoltaic panel has weak current or no current, the display will flash or turn off the display indication to save energy.

3. When the system is running abnormally, press the "Reset" key and release it, the system will automatically reset and restart. _" 1
V. Set the battery pack charging voltage. (Guo Wu Wu -
After the controller is connected to the photovoltaic panel, press and hold the plus and minus keys at the same time until the voltage setting screen is displayed. The charging voltage of the battery can be set by pressing the plus and minus buttons.
