Inverter Overview

Key features

Pure sine wave output – The output of the PD1200 Series inverter is a 120 VAC, 60 Hz, pure sine wave. Unlike a modified sine wave, a pure sine wave is ideally suited to drive all types of loads including refrigerators, motors, power tools, and common household electronics.

Integrated automatic transfer switch

Built into the PD1200 Series Inverter is an automatic transfer switch that engages whenever power is detected at the AC input port. In recreational vehicles this is often used to switch over to shore or generator power when it is available, reserving the battery power for later use. The transfer switch transition times are fast enough that transitioning from one source to another will not impede operation for most electrical loads.

The transfer switch transition times are fast enough that transitioning from one source to another will not impede operation for most electrical loads.

2x peak power rating
When starting inductive loads like compressors (found in common household refrigerators) there is a large surge in power draw during the initial startup. To supply this initial startup power the PD1200 Series Inverter has been designed to supply a peak power that is 2X its rated power.

Automatic restart after DC disconnect
The PD1200 Series Inverter will detect when the battery input connections have been removed. When the DC disconnect switch is reengaged the inverter will automatically restart. Similar to a DC disconnect switch, this automatic restart also kicks in when the user replaces the batteries. To avoid an automatic restart, simply turn off the inverter prior to disconnecting the batteries.

Under/over voltage protection
To protect both the inverter and the battery bank the PD1200 Series Inverter has been designed with integral under voltage and over-voltage protection. These voltage limits are designed to operate with a Lead Acid battery bank without damaging the batteries. The inverter may also be used with a 12V lithium-ion battery pack (LiFePO4) with a properly configured BMS. See Specifications on page 16 for voltage limits.

Reverse battery protection

Reverse battery protection has been added to the inverter to protect the equipment in the event that the positive and negative terminals of the battery are incorrectly connected to the inverter. Unlike some other inverters on the market, there is not time delay associated with reverse battery protection. In the event that the inverter is reverse-wired, it will not turn on.

Over‐load protection
In order to protect the inverter from over‐load conditions the power draw is continually measured, and should it exceed the rated output power, the inverter will automatically shut down and display the error code corresponding to an overload error. This is a required feature in all UL safety-certified inverters. For additional protection, the PD1200 Series inverter includes a 15A circuit breaker on the output to limit the power that is passed through from the AC Input.

Short circuit protection
In any power system, a sustained short circuit can cause hazardous conditions potentially resulting in overheating and fire. To avoid these conditions the inverter has been designed with short circuit protection. It will detect any large current spikes caused by a short circuit and shut down immediately to avoid damaging the inverter and output wiring.

Over temperature protection
A required feature for all UL safety-certified inverters, over temperature protection, is designed for every PD1200 Series inverter. When the internal temperature of the inverter gets too high due to poor ventilation or high ambient temperature the inverter will shut down. The output will automatically turn back on when the internal temperature returns to safe operating temperatures.

Thermally controlled variable speed fan
Using technology that is found in all Progressive Dynamics Converters, the PD1200 Series Inverter employs a thermally controlled variable speed fan. This fan will only turn on when the inverter is operating at warmer-than-normal temperatures. Furthermore, when it does turn on, the speed of the fan is smoothly controlled to only run as fast as necessary to keep the inverter within safe operating temperatures. This is designed to minimize disruptive audible noise.

Neutral Bonding

In an RV the neutral should be tied to the ground at the source of the power. To safely accomplish this, the PD1200 Series inverter ties the neutral to the ground only if the inverter is supplying the power. When the transfer switch is engaged to pass AC Input power, the ground connection is passed from AC input to AC output with the assumption that the neutral is properly grounded wherever the power is being generated (generator or campground electrical post).

WARNING

  • INVERTER SHOULD ONLY BE INSTALLED BY AN ELECTRICIAN OR A CERTIFIED RV TECH.
  • INVERTER SHOULD BE MOUNTED IN A DRY, WELL-VENTILATED SPACE WITH ADEQUATE AIR FLOW.
  • FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SERIOUS INJURY OR DEATH.

WARNING

  • DO NOT CONNECT ANY AC SOURCE TO THE AC OUTPUT WIRING OF THE INVERTER. CONNECTING AN AC SOURCE TO THE AC OUTPUT OF THE INVERTER WILL RESULT IN A HAZARDOUS CONDITION.
  • ANY DIRECTLY WIRED AC INPUT AND AC OUTPUT WIRING MUST BE PROTECTED WITH PROPER-SIZED CIRCUIT PROTECTION.
  • FAILURE TO FOLLOW THESE INSTRUCTIONS MAY DAMAGE THE UNIT AND/OR EQUIPMENT.

Inverter Display Features

  • Power Button: Press to turn on; hold to turn off
  • Select Button: Cycles between display states: Input Voltage, Output Voltage, Output Power, Sleep, Error Code (if applicable)
  • Power Indicator: Lights up green when the inverter is on
  • Fault Indicator: Flashes red when an error has occurred
