Tripp Lite's APS3636VR DC-to-AC inverter with automatic line-to-battery transfer and integrated charging system serves as an extended run UPS, a standalone power source or a truck/RV/Industrial inverter. Supplies up to 3600 watts of continuous 120V AC power from any 36V battery. OverPower inverter output feature temporarily provides up to 150% of the continuous output for 1-60 minutes and DoubleBoost inverter output feature delivers up to 200% of the continuous output for up to 10 seconds, providing the extra power needed to cold start heavy-duty tools and motorized equipment. When hardwire AC input is energized, commercial power passes through to connected equipment and the battery set is recharged via 3 stage, 30 amp charging system. In UPS mode, the APS system responds to blackouts and severe voltage fluctuations with a near instantaneous automatic transfer to battery-derived AC output. Includes a set of high current DC input terminals for simple installation (user supplies batteries and cabling - see owner's manual for recommendations). Passes sine wave utilty or generator power during battery charging and UPS line power operation, plus efficient PWM sine wave AC output in inverter and UPS backup modes. Built-in Automatic Voltage Regulation (AVR) corrects line power AC brownouts and overvoltages without using battery power during battery charging and UPS standby modes. Reliable large transformer design, with frequency control powers resistive electronic loads or large inductive motors, compressors and other items with high current needs on startup. Included APSRM4 wired remote power switch with full status LEDs provides remote power inverter on/off switching and continuous status information. Supports an unlimited amount of runtime with any number of user-supplied batteries connected. Highly adaptable to a variety of applications and site conditions with adjustable charger settings for wet/gel battery types and selectable line to battery power transfer voltages.

NOTE: To protect against high current draw that may occur during inverter failure, a fuse link rated at 300a should be positioned no more than 18" from the APS3636VR's battery in the positive line.

Key Features

  • APS3636VR serves as a truck/RV/Industrial or stationary DC-to-AC inverter with automatic line-to-battery transfer and integrated battery charger

  • Moisture-resistant construction enables vehicular or marine operation in high humidity environments
  • 3 position operating mode switch supports "AUTO" mode to enable automatic transfer between DC and AC modes, CHARGE-ONLY to maintain a full battery charge when AC is present without auto transfer and SYSTEM OFF settings
  • Set of six front panel LEDs display AC/DC operational modes, overload status, DC voltage level, shutdown status and system fault status
  • Set of 4 configuration dipswitches support wet/gel battery charging profiles, adjustable 135/145V high voltage auto transfer during overvoltages and selectable 75/85/95/105V AC low voltage auto transfer during brownouts
  • Resettable 25A charger AC input breaker and resettable 30A AC output breaker and automatic 2 speed cooling fan protect the inverter from load and temperature related failures
  • Grounding lug properly connects the inverter/charger system to earth ground or vehicle grounding system
  • Automatic overload and thermal shutoff safely turns off inverter as excessive loads or overheating conditions develop
  • Load sensing control dial enables adjustable load threshold required to automatically turn the inverter on and off in DC mode as load conditions change

Typical Applications

  • Versatile inverter/charger system with auto-transfer switching serves as a truck/RV/Industrial inverter for RVs, over-the-road trucking, conversion vans and fleet service vehicles; a standalone alternative power source for off-grid, alternative energy or export applications and as an uninterruptible power supply (UPS) for items compatible with a 16.6 millisecond transfer time. NOTE: For sump pump applications, Tripp Lite recommends its "UT" Utility Truck Inverter/Chargers.

Comments about Tripp Lite PowerVerter APS 3600W 36VDC 120V Inverter/Charger with Auto-Transfer Switching Line-Interactive AVR:

when i need this kind of verter i went to the market and look for these kind of it verter from many of shops , when i saw your product i ask about it ,they give me a lot of Characteristics , i was impressed by my brother and I asked where he was an electronic engineer and impressed by the specifications and advised me in your equipment.
I asked also an electrical engineer who works for the institution that I work with and advised me your equipment because my foundation used the same kind yours.
I live in the Republic of Yemen in Sana'a city and work in the Social Fund for Development and since our city is under power outages always The Fund uses the devices to store electricity, as well as most of the houses, and since I lived in my new house you need to stockist of electricity so I can take advantage of the electricity in case of interruption

Comments about Tripp Lite PowerVerter APS 3600W 36VDC 120V Inverter/Charger with Auto-Transfer Switching Line-Interactive AVR:

I use an APS3636VR with 3 AGM deep cycle batteries to provide backup power for our house in the Bahamas. The inverter powers our water pump, refrigerator, coffee pot, lights in the living areas and fans. It switches automatically when the city power fails, takes care of the recharging of the batteries in a trouble free way. The only problem I have had is that it will not drive the long internet cable supplied with the remote control unit. When I use a short (3 ft) cable it works well.
