PowMr Solar Inverter Charger 3KW 120V AC MPPT 60A Solar Charge Controller PV 100V Lithium Battery And Lead Acid Battery

Pow series is a new hybrid solar charge inverter, which integrates solar energy storage & means charging energy storage and AC sine wave output. Thanks to DSP control and advanced control algorithm, it has high response speed, high reliability, and high industrial standard. Four charging modes are optional. Based on full-digital intelligent design, the DC-AC inverter module employs advanced SPWM technology and outputs pure sine waves to convert DC into AC. It is ideal for AC loads such as household appliances, power tools, industrial equipment, and electronic audio and video equipment.

Installation

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

Easy to hook up and install
Comment
Works as it should so far havent hooked in solar yet. But grid tie and batteries work. Currently have it on a 15amp cord so when I'm working in the trailer and my demand is higher than that it automatically transfers to the inverter and batteries and keeps me going I am thus far very pleased with the system.Only thing that would be nice is if programing was more user friendly or intuitive.

Powerful all in one unit for Van Conversion
Comment
Just received the unit and haven’t used it yet. Feels sturdy and well assembled. I will be installing it in a van conversion soon and will update after I get it live.I will have 700watts of solar on van roof and 277ah lifpo4 battery.Update:It's all installed and running fine.In the off-grid mode, I loaded up to 2000watts (lights/fan/electric water heater) and it had no issue. The cooling fans will kick on at that load level which do contribute a bit of noise.It is important to follow the clearances for installation for cooling, especially if the unit is mounted in a warmer location and/or will be loaded up heavily with electric loads.The next day when the sun comes up it recharges the bank from the solar.I have my van shore power connection wired directly to this unit. When I'm plugged into shore power it tops off the batteries if needed and provides any AC and DC power needed for loads.These settings are all adjustable which is great.

Working

Battery Four Charging Mode:

  • CSO: Solar energy will charge battery as priority. Utility will charge battery only when solar energy is not available.
  • CUB: Utility will charge battery as priority. Solar energy will charge battery only when utility power is not available.
  • SNU (Default): Solar energy and utility will charge battery at the same time.
  • OSO: Solar energy will be the only charging source even if utility is available.

Three Load Working Mode:

  • SOL: Solar energy provides power to the loads as priority, then Battery, then Utility AC power.
  • UTI(Default): Utility will provide power to the loads as priority, then Solar and Battery power.
  • SBU: Battery power load first, then Utility.

This PowMr off grid solar inverter all-in-one does not support parallel operation, and does not support phase separation!

ee

AC Output Wiring NOTE:

  • Only the Live and Neutral wires will be connected to the Output Terminal Block, the Ground will be connected to the screw terminal.
  • Make sure any circuit breakers are disconnected and ensure the unit is in the off position.
  • AC Output should NEVER be connected to public power/utility or a generator.

Warning:

  1. >span class="a-list-item">Never install the all-in-one solar charge inverter and lead-acid battery in the same confined space! Also do not install in a confined place where battery gas may collect.
  2. Ensure that there is enough air flowing through the heat sink, and space of at least 200m to the left and right air outlets of the inverter shall be left to ensure natural convection heat dissipation.
  3. This 3000W Solar Inverter is suitable for 24V battery banks systems ONLY
  4. For PV to charge 24V battery banks, you will need a minimum PV Voc voltage of 34V DC.
  5. The bluetooth module has been discontinued, and the wifi module needs to be purchased separately!
  6. This PowMr off grid solar inverter all-in-one does not support parallel operation, and does not support phase separation!
