Inverter/Charger UPS System
1250 Watts 120Vac output with 30A 12Vdc Charger
This is an alternative energy source for every situation. Tripp Lite's versatile APS Series of high-efficiency DC to AC inverters offers an alternative source of affordable AC power in both off-grid and emergency situations. An APS Series Automatic Power System can be used in a variety of ways For a better understanding of this unique device see our comparison of the APS Series with traditional UPS Systems.
Tripp Lite's APS1250 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 an automotive inverter. Supplies up to 1250 watts of continuous 120V AC power to 2 AC outlets from any 12V battery or automotive DC source. 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 AC cable is connected to a live wall socket, 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 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 utility or generator power during battery charging and UPS line power operation, plus efficient PWM sine wave AC output in inverter and UPS backup 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. Optional APSRM4 wired remote power switch with full status LEDs provides remote power inverter on/off switching and continuous status information (APSRM4 sold separate). 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.
Versatile inverter/charger system with auto-transfer switching serves as an automotive 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..

1) Select and size batteries based on your total expected load and run time. Use one of the following two plots. Read the number of Tripp Lite #98-121 gel cell batteries from the left plot, or if you plan on using other batteries read the required amp-hours from the right plot.

2) If you are purchasing batteries elsewhere, be sure to use only the proper types as described above. We DO NOT recommend using standard vehicle starting batteries as these will wear out after only a small number of discharges. Use only "deep cycle", marine or golf cart batteries. To make your battery connections as safe and simple as possible order our universal battery cable set and fuse for this inverter, CABSET1012.
3) This unit is not large enough to power most sump pumps. Use one of our larger APS units such as the APS2012 or APS2424. If you have a high efficiency sump pump motor the APS1024 may also have sufficient capacity. Click here for some high efficiency sump pumps. If interested in these request a quote by e-mail.
