Review: A Top Quality Inverter With Superior Features - Update: My mistake from the previous update. There was a loose connection making it appear that the inverter was drawing too much current from the batteries. After solving the connection problem, the inverter is working perfectly as it has been for months. As long as you do not pull above 800 watts despite its 1200 watt rating, it should work well for any PV system. Update: This inverter must have a no load power draw of from 70-100 watts, a level that is unacceptable. My new LiFePo4 batteries will rest at 26.5 volts for my 24 volt system until I turn on this inverter. Suddenly the batteries dive to 24.7 volts just from the inverter with no load. I adjusted the settings with no luck. The fan runs all the time even with no load. Eco more is useless because it cycles power on and off ever few seconds. This inverter has serious design flaws unfortunately. The only good aspect is that it can handle 29.2 volts when charging. Original review: I have only run it for 24 hours. Reliability will only reveal itself after two years of use, but it has produced clean power with very low fan noise. I will be ordering another one as back-up. Of the many inverters I have purchased over the years, this one appears to be both the highest quality one, with the best features, at the best value. Most other inverters will shut down once the batteries exceed 28-29 volts. This one will stay on at 30 volts, more than sufficient to handle intense sunny days when batteries can hit 29 volts.
Review: Great features and works fantastic - 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 desertcart. 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

### ⭐⭐⭐⭐ Worked initially, developed problems later
*by B***A on May 19, 2022*

The Ampinvt 800 W pure sine inverter arrived days ahead of schedule and in seemingly perfect order. The model number is HT-80112. It came with battery cables, a pleasant surprise. It also came with a US-style IEC appliance cord, a more puzzling surprise. True to other reports, the hot and neutral are swapped on the internal receptable, which otherwise works fine. It's easy to use the terminal block to bypass the faulty outlet. The cooling fan is on all the time, but at a fairly low speed when the unit is just charging the battery and passing AC straight through. The idling power draw in AC priority mode came out to about 15 watts. Placed in ECO mode it couldn't start up fast enough to keep a Raspberry Pi 4 computer running when the AC was disconnected. In normal AC priority mode UPS operation seems perfect. It's able to start a refrigerator with a 7.1 amp nameplate current draw with three beeps worth of overload warning. It settled down to about 13% load. No odd noises or other trouble signs. A Raspberry Pi4 and monitor powered at the same time wasn't detectably perturbed. A few experiments with an adjustable 1500 watt heat gun revealed that near 50% load the battery cables started to get hot. No damage, but a fair warning. On balance it seems a nice unit. If it lasts it'll be a good buy. [update 20240414] When I purchased the second unit it displayed faulty behavior of the charge indicator LED, continuing to flash even after the battery was fully charged. My complaints to tech support were met by evasive and distracting replies that made pointless requests and served only to delay progress. Eventually I gave up, since the crazy LED seemed harmless and the inverter worked ok otherwise. Now the charging LED has simply gone off and stayed off. The device still seems to work. Because of the very low price the inverter remains worth trying, but I'd urge purchasers to immediately test thoroughly any unit received and return it without hesitation for a refund in the first 30 days. Don't wait for tech support! [added March 2, 2025] The second (faulty) inverter continued to operate even with the non-functional charging LED, which simply remained off even when charging the battery. However, the fact that the overload beeper occasionally sounded three beeps suggested the inverter was slightly undersized for the job. A 1200 watt version of the same inverter seems to work a bit better. It sometimes beeps once on compressor startup, but not more. No other problems so far. it came with 16 square millimeter battery cables, versus the 10 mm square cables of the 800 watt version, and no IEC cord, which was useless anyway. bob prohaska
