LiTime 3000W Pure Sine Wave Inverter Charger, 12V DC to 120V AC Inverter w/LCD Remote Panel, 5A to 45A Adjustable Charging Current, Surge 9000W Inverter for UPS, RV, Home, Boat

I researched inverters extensively before settling on this pure sine wave model by Li Time. I probably didn't need a 3000W model but better to go slightly overboard than to come up short.I ordered this and upon receipt I hooked it up per the instructions, using the proper gauge wire and mounting procedures. After 24 hours it malfunctioned. I disconnected everything and tried it again in a couple of days, and the same thing occurred again. I contacted LiTime and Wendy was very helpful. After eliminating certain possibilities (as all tech support will do) I was sent a return label. I returned it, and in a few days I received a replacement that appears to be a slightly updated model, which is a good thing. I have run it through its paces and it seems to function very well. I am using it as a backup for a sump pump, and it will only come into play if we're having flooding AND a power outage, so it will see minimal use, but absolutely vitally important if those conditions come about. I hooked it up to two 6v golf cart batteries wired in series with 1/0 cable. I used a 12 AWG wire for the AC supply cord. The instructions say to use 10 AWG, but the wire on that circuit is 12 AWG, so using 10 AWG would be pointless. When everything is hooked up and turned on, initially the unit goes to fast charge and the fan runs, and when it senses that the battery voltage is suitable, it reverts to float charge and the fan shuts off. When grid power is lost and it senses a load, it instantly reverts to inverter power and provides AC voltage. When grid power is restored, it goes back to grid mode and appropriately charges the battery. It's very quiet, and is a hands-off operation, which is a very important consideration in my situation.The unit is, naturally, very heavy, and I mounted it on the wall above the pump and the battery box, and it required a little help from a friend to mount, but otherwise it was very straightforward. To do the whole install yourself, you need to be able to crimp and/or solder, you need to be able to use heat shrink tubing (provided), and you need to have a basic understanding of AC and DC voltage. The AC supply cord is NOT a plug-in deal, you have to solder the ends onto the wires and attach them to their correct terminals. You have to know how much to strip back so there's no exposed wire when you're done, and to properly install the safety covers provided. This isn't a job for someone who takes shortcuts on their projects. Do it right and everything will be ok, mess up somewhere and you may have trouble.I caught this at a very good price, so I'm well pleased about that. The design of the unit is very modern and attractive and appears well made and of high quality.

I installed this in my electrical system in my camper van. It worked ok at first, it is a little loud when the inverter is going. Output is 110V (not 120V if you need that). Unfortunately mine failed within the first day running a 1500W resistive heater and I decided to return and buy something that is higher quality.Still love my Li Time batteries and also have an MPPT and DCDC charger from them that are ok.

Great inverter for the price point. It just did not do what was needed which is to produce 240V with two inverters to a single panel. If you were making a 3KW 120V circuit, this little machine is the way to go. Might have to buy another and put in the shed to run a coy pond and lights.

This unit replaced a 1800 watt similar unit that was mistakenly drill through by a RV repairman doing work from underneath. The old unit had the same features and always operated well. We only have small loads.. A small refrigerator (100 watts, 75 watts during a normal cycle) t.v and a couple LED lamps (3 watts each). This LiTime 3000 will only operate 45 minutes with the lamps, when the refrigerator kicks on the lights go out.. Both 100 amp batteries removed and tested, Full capacity.Replaced with a 2000watt Renogy, All is operating well.This unit(LiT3000) was purchased 5 months ago. The time, labor and energy wasted on this miserable product can not be recouped, but hopefully this will save someone out there.

purchased a "12v 3000w Inverter-Charger" that arrived on time.Using it to convert my toy-hauler fully to Solar so it is not dependent on the Generator or Shore power.Used it with two 360ah lithium LifePO batteries.Originally used 4AWG-Gauged battery cables... The wire coatings fried/melted/smoked/caught fire.(I believe those 4awg cables to be poor quality and defective now, but 1/0awg gauge is what the manual calls for... so I'm using those now.)Reached out for Support.Wendy at Li-Time recommended the product-prescribed 1/0awg gauge cables.She also asked about all electronic devises that would be utilized.2 A/C Units, TV Microwave, Refrigerator, etc.She also asked what solar controller I was utilizing.Once I supplied all info, she advised my load is not enough to cause this issue.(This was confirmed by my shunt).Wendy referred me to the battery manufacture to determine (BMS) if Battery Management system was an issue... maybe not being triggered or woke.I believe the issue was with the battery BMSs.Wires do not get exceeding hot and running both A/C Units only requires about 88amp when running... about 118amps when starting up.All support emails were responded to within 1 business day.Exceptional post-purchase service was provided.Very pleased with this company and its product.

Been using for six months, incredible value for the money. Only issue is when it switches from shore power to battery, the lag time is long enough that my starlink has to disconnect and reconnect.

The batteries and the inverter worked perfect. And their customer support is excellent. I really like the individual Bluetooth connection to each battery.

It never charged the battery, left me practically stranded. You get what you pay for, maybe I can sell it for $200, I ended up getting a 3000W GoPower
