Features

  • This Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch. High transfer efficiency is above 90%, , complete isolate surge interference of input & output's voltage and current, Impact resistance, super load capacity, built-in AVR stabilizer, continuous stable pure sine wave output.
  • Battery typesetting choose : SLA / AGM / GEL / Li-ion battery & Customize. Support lifep06,Sealed Gel AGM Flooded Lithium Batteries
  • Adjustable Charging Current: The max charge current can be adjusted from 0%-100%, 100% is max charge current 15A. Setting the value to 0% will turn off the charging function.
  • Five working mode : AC priority mode / Battery priority mode / Generator mode / ECO mode / Unattended mode. When AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. When you choose battery priority, the inverter will invert from battery dc to ac output . Battery priority mode & Unattended mode have Low volt restore setting and Low volt protect setting.
  • Protections: Battery low voltage alarm / Battery high voltage alarm / Over temperature protection / Over load protection / Short Circuit protection. 110%-120% of the output was maintained for 30s, then the output turned to bypass, more than 160% maintained the 300ms.

  • Great features and works fantastic
Size: HT-800W12V
This review is for the HT-80112, the 800 Watt unit. I received it Oct 19, 2022 and was pleased to find that cables were included with the unit. I cut the positive cable and attached crimp lugs to each cut end, and inserted a 175 Amp fuse from O'Reilly's. I also checked the output connector that I expected to be miswired after reading the other reviews. Mine is wired correctly. I initially found the menus a bit funky, but they actually work fine once you get the feel for them. I set my unit up for AGM, 20% charge rate, unattended mode with dropout at 11.5 V and restore at 12.5 V. I hoped to find that with input power disconnected the inverter would operate until the battery voltage dropped to 11.5 V, at which time the unit would wait for utility power to be restored. Note that as shipped, the dropout voltage is set for 10 volts. I tested the unit with my router, the fiberoptic internet interface, a security system, a microprocessor, and a 75 Watt incandescent bulb for loads. I used the old battery I took out of my pickup, so it only ran a couple of hours, but it worked exactly as desired. When I restored power the battery started charging and completed charge normally. Initial charge rate was around 13 Amps. I've pulled power several times and all the equipment stays online. This unit does exactly what I need and has an excellent price. All the connectors are quality and well placed. My one criticism is that the marketing is inadequate. It was unclear to me when I ordered the unit that I could set the dropout voltage, which is critical for unattended operation. I emailed the manufacturer twice before I received the unit and received responses each time within 24 hours. I tried unsuccessfully to find a manual for the unit on their website, but was sent one by the manufacturer. The FT series has manuals available for download, but it seems the website hasn't been finished for the HT series yet. I next bought the UB121000 100AH battery from Amazon. I ended up setting the dropout voltage for 12.0 volts and using the Lithium Ion/Customize menu set the float voltage to 13.6 volts. The only time my battery will be under load is if the power goes off, and all I really need is either to ride through a power glitch, or have a clean shutdown and a clean startup when the utility power comes back online. I've attached photos of my inverter waveforms with my 35 Watt load attached. The inverter isn't quite as pure as utility power, but it isn't bad. One photo shows the transition from utility power to inverter, and the other shows the transition from inverter to utility. Inverter to utility looked identical in various captures. I only did the one capture of utility to inverter, which happened when I pulled the wall plug to the inverter. One nice thing is when you restore utility power the inverter waits a couple of seconds before it switches back to utility power, so the glitch you sometimes see when utility power is coming back online is masked. I initially thought I might use the unit to equalize an older flooded cell battery, so I set the float voltage to 15.5V. I never got a straight answer out of their tech support as to what the unit is actually capable of, but it isn't 15.5 Volts, even though you can set it in the menu. I did see it maintain 14.7. The specs in the manual show DC input voltage: 10.5 to 15 volts. I discharged my UB121000 battery for 15 hours for a total of about 42 Amp Hours to around 12.23 volts. It was mostly recharged in about three hours, but I was still seeing around 100mA of charge current 24 hours later. This unit has all the features I need and works great. I couldn't be happier with it. Oct 31, 2022 ... show more

  • Perfect sump pump power outage backup .
Size: HT-1200W12V
This item works perfect to keep my sump pump running if the power goes out. Good build quality, easy hookup. Getting it setup (programmed) is a bit tricky. I have not figured out if I can set a minimum voltage for cut-off and the cooling fan runs all the time even when the unit is not working as a passthrough when shore power is on or when its using the battery. When its running an item the fan speeds up even more. It is loud enough I can hear it upstairs. I think the fan should only run when the unit is actually powering an appliance. I tested it by turning off the breaker feeding it while the sump pump was running. Instantly switched to battery power. When grid power is turned back on it starts re-charging the battery. It keeps the PowerQueen 100ah battery topped off . Once setup, there is nothing more you need to do. Been using this for a few months now with zero problems. Peace of mind when im away from home. ... show more

  • Works great as a UPS for my 3D printer
Size: HT-1200W12V
Seems to be a well-designed and manufactured inverter. I use it as a long run time uninterruptable power supply for my 3D printer. 3D prints can take many hours to complete, and electric grid repair can also take many hours to complete, so a standard UPS would not have provided enough battery backup for the print to finish. The Impinvt 1200w coupled with 2 large deep cycle batteries is just the ticket for success. The only downside I can list is the battery cables are pretty cheap and probably need to be replaced if you are going to use this inverter at its maximum 1200 watts. ... show more

  • Original DOA, replacement works as intended.
Size: HT-1200W12V
Original: The unit I ordered arrived defective. The LCD was nonfunctional, although the backlight did illuminate. The indicator lights worked expected, and the service receptacle problem noted in other reviews was present, however without the ability to configure the unit I cannot blindly keep this connected this to a good battery for any significant period. Updates to follow examination of the replacement unit. Update 1: I received the replacement unit. Without power there is continuity between line and load sides of W and G, and not L1. The original unit battery light was green, while the replacement unit battery light is yellow. The original unit was missing battery conductors and yet for some reason had a standard PC 5-15P/C13 power cable. Update to follow with a scan of the manual and, following that, a menu button flowchart. Update 2: The second unit has performed well. I do wish the battery settings had separate charge start and charge stop settings to allow for different resting and charging voltage, but it does not. I have added manual photos. ... show more
