## Description

Ampinvt 800W Pure Sine Wave Inverter with AC Charger, DC 12V to AC 120V Output,UPS Backup Power Low Frequency Inverter for Lithium, Sealed,AGM, Gel,and Flooded Batteries

## 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 LifePo4，Sealed Gel AGM Flooded Lithium Batteries
- Adjustable Charging Current: The max charge current can be adjusted from 015A, Setting the value to 0A 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.

### ⭐⭐⭐⭐⭐ 2 Years of Continuous Use And Still Working! (1200 Watt Version.)
*by B***R on April 15, 2025*

I am using two 1200 watt versions. They have been hooked up continuously for two years now charging two separate 8-battery banks comprised of 12V deep cycle SLA 97 AH marine batteries that were all purchased at the same time. I did this setup to have backup power that could be charged and maintained via a/c power and act as a backup for key systems. It does so by immediately switching to battery power when wall power goes out. When there is power from the wall the unit output functions as a pass-through for that power while also keeping the batteries charged or recharging. It has worked so well that I am buying their solar chargers too.So, here is my setup and what you might want to know:1. There is a setting in the instructions on how to set up for Standard Lead Acid Batteries. After doing some research I decided to pair 8 deep cycle 97 Amp Hour 12 Volt Marine batteries with each unit. You have to set the the charge current at 80% from what I recall but I cannot find the settings right now to verify. This setting matched the charging current to the battery bank size and type. You just hook them up in parallel. I also purchased short and thick gauge connectors from Interstate Battery. After that you hook the positive lead from the charger to one side of the bank on the positive terminal and the negative end to the other end of the bank on the negative terminal. This will keep all batterie in an even state of charge.2. It costs around $8/month to keep the batteries topped off at around $0.14/kwh.3. When the power goes out this thing does not miss a beat. You cannot even tell. No blips no nothing. I have security cameras, deep freezers and incubators plugged in and they just keep running as if nothing happened.4. Two year old SLA Deep Cycle batteries are at 97% charge state according to the display.5. The only bad part is the relatively loud fan. I have my banks in two parts of the house so hear them a lot. The good news is they run slower most of the time. There seems to be different speeds. After a while the noise drones in the background and is only noticed when the speed changes.6. You will need to buy a three-pronged plug and wire to get power from the wall to the unit. I checked the configuration beforehand and found that it was fine and not reversed as some people reported with the 800W version. That was just not the case with the 1200W units.

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

The Ampinvt 800 W pure sine inverter arrived daysahead 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, amore puzzling surprise.True to other reports, the hot and neutral are swappedon the internal receptable, which otherwise works fine.It's easy to use the terminal block to bypass the faultyoutlet.The cooling fan is on all the time, but at a fairly lowspeed when the unit is just charging the battery andpassing AC straight through.The idling power draw in AC priority mode came out to about15 watts. Placed in ECO mode it couldn't start up fast enoughto keep a Raspberry Pi 4 computer running when the AC wasdisconnected. In normal AC priority mode UPS operationseems perfect.It's able to start a refrigerator with a 7.1 amp nameplatecurrent draw with three beeps worth of overload warning. Itsettled down to about 13% load. No odd noises or othertrouble signs. A Raspberry Pi4 and monitor powered at thesame time wasn't detectably perturbed.A few experiments with an adjustable 1500 watt heat gunrevealed that near 50% load the battery cables startedto 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 thecharge indicator LED, continuing to flash even after the battery wasfully charged.My complaints to tech support were met by evasive and distractingreplies that made pointless requests and served only to delay progress.Eventually I gave up, since the crazy LED seemed harmless and the inverterworked ok otherwise.Now the charging LED has simply gone off and stayed off. The devicestill seems to work.Because of the very low price the inverter remains worth trying, butI'd urge purchasers to immediately test thoroughly any unit receivedand return it without hesitation for a refund in the first 30 days. Don'twait for tech support![added March 2, 2025]The second (faulty) inverter continued to operate even with thenon-functional charging LED, which simply remained off evenwhen charging the battery. However, the fact that the overloadbeeper occasionally sounded three beeps suggested the inverterwas slightly undersized for the job. A 1200 watt version of thesame inverter seems to work a bit better. It sometimes beepsonce on compressor startup, but not more. No other problemsso far. it came with 16 square millimeter battery cables, versusthe 10 mm square cables of the 800 watt version, and no IECcord, which was useless anyway.bob prohaska

### ⭐⭐⭐⭐⭐ A good value for the buck.
*by T***D on July 14, 2025*

This is a small low voltage inverter/charger that is chock full of features for the price.It works well as a UPS and battery charger as well as being a great 12V Inverter. We use it in a camp bus to run lights, TV, soundbar, Mini Fridges, and a blower fan.It is not to noisy.The terminal connectors for the battery and AC input/output are well sized and secure well.It does what it is advertised to do, and does it well.
