    Please read this manual carefully and familiarize yourself with the installation procedures before installation.

    Installation Safety

    The unit should be installed in a well-ventilated, cool, and dry environment. Make sure the fans of the unit and the ventilation holes are not blocked.

    Do not expose the unit to rain, moisture, snow, or liquids of any type.

    Never install the inverter in a sealed enclosure with flooded batteries. Gas can accumulate and there is a risk of explosion.

    Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.

    Location Recommendations

    Ensure installation follows the following guidelines:

    1. Cool, dry, well-ventilated area — Heat is the worst enemy for electronic equipment. Inverters must be in an area where the fans are not blocked or where they are not exposed directly to the sun. They should be in an area free of any kind of moisture and allow for clearance of at least 8” around the unit to provide adequate ventilation.
    2. Protection against fire hazards — the unit should be away from any flammable material, liquids, or any other combustible material. The unit can spark and the consequences could be severe.
    3. Close proximity to battery bank—prevent excessive voltage drop by keeping the unit close to the battery bank and having a properly sized wire going from the battery bank to the inverter.
    4. Limiting electromagnetic interference (EMI) — ensure the inverter is firmly grounded to a building, vehicle, or earth ground. Keep the inverter away from EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage/interference to the equipment.

    Other Precautions:

    • When installing the battery, be very careful, when installing lead-acid liquid batteries, you should wear protective glasses, once in contact with battery acid, please wash with water in time.
    • Avoid placing metal objects near the battery to prevent short circuits in the battery.
    • Acid gas may be generated when the battery is charged so ensure good ventilation around the environment.
    • Incorrect or improper connection points and corroded wires can cause great heat to melt the wire insulation, burn surrounding materials, and even cause fire, so ensure that the connection is tightened
    • It is best to avoid mobile applications when the wire shakes and causes the connection head to lose. Outdoor installation should avoid direct sunlight and rain, snow.
    • Do not install the solar inverter in harsh environments such as damp, greasy, flammable, and explosive areas or where dust accumulation is high.
    • The municipal electrical input and AC output are high voltage, do not touch the wiring. Do not touch the unit when the fan is working.
    • To avoid damage, do not use more than one (in parallel) input AC power supply.

    Please Note: While the Solar inverter has fans for cooling, this installation location optimal for natural convection cooling will improve the overall efficiency

    the spec for max panel input voltage shows 100-150. Does that mean you have to have a minimum of 100v ?

    How can I get 240 v ac split phase
    Administrator reply
    Hello, our service will contact u soon.
    What devices can be charged/powered by PowMr‘s 3000W solar inverter 110V?
    How to choose the solar panel and what is the charge time?
    Does this solar inverter limit PV current? Am I not getting my full power?
    Does it come with the pictured wifi module?
    Can utility charging and inverter output run at the same time?
