Product Introduction

Summary 
Our PICOGLF series off-grid inverter is one of the largest DC to AC inverters in the world. The Global LF Series Pure Sine Wave Inverter is a combination of an inverter, trickle battery charger, and an AC auto-transfer switch into one complete system, with a peak conversion efficiency of 94%.
It is packed with unique features and it is one of the most advanced inverters on the market today. It features power factor correction, customizable AC and DC  operation, and a pure sine wave output with unprecedentedly high surge capability to meet the demanding power needs of inductive loads without damaging the equipment.
When utility AC power cuts off (or falls out of acceptable range), the transfer relay is de-energized, and the load is automatically transferred to Inverter mode.  Once the qualified AC power is restored the relay is reenergized and the load is automatically reconnected to AC bypass mode.
The priority is programmable.

Technical Information

Derating
Reducing the output power is a way to prevent inverter overload or damage. When the operating environment temperature and altitude are too high, both can cause a decrease in the inverter’s output power.

η=（Pout/Phnom ）x100
T = environment temperature
Pout is the off-grid inverter’s actual maximum output power Phnom is the off-grid inverter’s allowed max. output power

Installation

Location

• The inverter must be installed in a cool dry area. Water, dirt, and dust will damage the inverter.
• A 1ft clearance around the inverter is recommended.
• Installation must comply with local standards and codes.
• Do not install the inverter in a flammable or explosive area or a place where flammable or explosive materials are stored.
• Do not install the inverter in areas where the inverter is vulnerable to lightning strikes.
• Do not install the inverter in a high salt, humid environment.
• Inverter has a rating of IP20. Install indoors and out of direct sunlight.
• Place inverter on a solid, sturdy, flat surface that can handle the inverter’s weight.
• The ideal temperature should be maintained within -13 to 122°F and humidity not exceeding 95%.
• The inverter should be installed vertically.
• Do not allow the inverter to tilt forwards.
• Never install the inverter horizontally.
• Install the inverter so the LCD is easy to access and read.
• The inverter should have plenty of airflows all around the inverter for proper cooling fan operation.
• Don’t install the inverter where passersby or children can tamper or access the unit.

Electrical Connection

As mentioned several times in this manual, installation should be done by a licensed professional. The electrical connections should be tested immediately after the installation is completed.

Prechecks

• All electrical connections must meet local electrical codes.
• Incorrect wiring and/or installation may damage the inverter and may cause bodily harm.
• Before making any connections or performing maintenance to the inverter, make sure all
• power is off and no voltage is present on the AC and DC sides.
• Test for correct grounding, using proper cable and fuse sizes.
• Use a fuse or breaker 12 inches off the battery bank.
• Confirm the front panel breakers are in the “OFF” position and confirm all connections are properly wired.
• Check that the DC input breakers are in the “OFF” position.
• The cable between the battery and the inverter should be as short as possible to avoid voltage drop.
• Never turn off the DC input breaker with the inverter on or under a load, damage to the breaker or the inverter will occur.
• Ensure all air vents are free from obstructions and clear of dust and debris.
• Don’t connect the ground wire (PE) of the cabinet and the neutral wire (N) together.

NOTE: Do not over shut DC breaker off during operation. To shut AC off, use AC breaker first, then disengage AC start switch. To shut down the inverter completely, follow the above steps first then turn off the DC breaker. Shutting off the DC breaker during operation and under a load will damage the breaker and cause arcing.

Warning！

• Do not reverse the polarity when connecting to DC input terminals. Confirm your wires are connected properly. Use the proper size cable and use the bigger cable to handle voltage drop for long-distance runs.
• REVERSE POLARITY IS NOT COVERED UNDER WARRANTY.
• Source ground to case ground must be isolated and wire length should be as short as possible.
• After all wire connections have been made, check all voltages to ensure the voltages are within the inverter’s specification.
• Never operate any inductive motor larger than 30% of the output of the inverter due to high startup surge.
• When turning on the DC input breakers, the breaker may trip or pop the first time. This is normal as the large capacitors are rapidly charging. If this happens, simply reset the DC breakers.
• When powering on the inverter, we recommend turning on the output circuit breaker first, then turning on the start switch allowing a soft start of AC loads to avoid any damage by large inrush current to inverter.
• Before performing checks or maintenance, open (off) AC breaker, turn off start switch, then open (off) DC breaker. Wait 5 minutes for energy to dissipate.  Measure DC and AC voltages with a multimeter and ensure there is no voltage between the DC side and the AC side. The display will slowly dim and disappear as the voltage drops. The inverter may still be live and have voltage present in the off position due to the large capacitors. Never touch any connection prior to testing with a multimeter.
• When the inverter is operating normally, it is typical to see a rise in temperature. The cooling fans will start when the temperature reaches @ 113°F.
• Do not open the inverter’s door or touch any wire while in operation.

NOTE
When the inverter is running, it is normal for the inverter to get warm. To avoid injury, only touch the LCD display and start/stop the switch. DO NOT TOUCH  ANY BREAKERS WHILE THE INVERTER IS OPERATING. THIS MAY CAUSE BODILY HARM AND RUIN THE INVERTER. After all connections are made and voltages are verified with a multimeter, proceed to the startup procedure in section 6.
