Note: Different types of loads have different starting impulse currents. Customers need to select the appropriate inverter model according to the actual equipment power, current, and load characteristics.
What kind of the inverter is suitable for your appliances?
Pls know that load is divided into resistive load and inductive load .If you need the inverter to run the resistive load (like laptop, TV, electric cooker ), please choose the inverter with continuous power higher than the appliance’s rated power. And it is best to use 80% of the rated power. If you use microwaves, water pumps, air conditioners and other appliances with motors or compressors ,please choose the inverter whose continuous power is 3-10 times higher than your appliances.
Working Mode Setting:
1. AC/Line priority mode — always use ac power as priority input, provide ac output, and automatically charge the battery.
2. Battery priority mode — Priority should be given to battery power supply. After low voltage protection, the battery will be transferred to ac grid power supply. When the battery is full, the battery will be transferred back to battery power.
3. ECO Mode—Load < 10% automatic sleep and stop output, load > 10% automatic boot back to normal inversion.
4. Generator mode — The generator is connected to the AC input of the inverter, and the output is stabilized through AVR while the battery is recharged.
5. Unattended Mode—When the battery is low voltage, the inverter goes into standby state(Power saving state). When the battery restores the voltage value set by yourself (such as solar charging), the inverter will restore the normal output of the inverter, and realize unattended full automatic operation!

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.
Customers say
Customers find the inverter functions well, with one mentioning it works perfectly for reef tank backup systems, and they appreciate its top quality construction and easy setup. The battery charging capabilities and power capacity receive mixed feedback – while some say it keeps batteries charged effectively, others report issues, and while some praise its 3600-watt surge ability, one customer notes it cannot maintain 110v on a 50% load. The noise level and fan operation also get mixed reviews, with some noting very low fan noise while others mention a relatively loud fan that runs continuously. Customers consider it good value for money.

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.

Worked initially, developed problems later
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

Easy setup, menu settings, great all in one combo for a LifePo4 UPS
Received this 800w/12v Charger / Inverter, it was well packaged, came with 2×10 mm cables.It requires a battery connection in order to turn on, so you cannot just wire it into AC power by itself. Setup through the menus was pretty straightforward and I was able to set up my lifepo4 battery with a charge rate of 14.6v as custom/lion setup, and disable the annoying beeping.Max charge rate is around 15A (~220w measured) and standby consumption of this all in one is 9.5w.Testing a cut from AC, I have no interruption to consuming devices. I don’t have tooling to test sine wave output tho.Low noise, with consistent airflow, fan runs 100% even when not under load, an improvement could be lower fan curve when not under load or low temperature.Lastly, I checked if there was any wiring issue and found none for the AC output, as shown in the photo, correctly wired as per indicator.Would have been great to see usage in watts vs load % on this unit. I tested burst of 1600w using a heat gun and saw the fault indicator light up with load shooting over 150%
