3000W Inverter

been in service now for a week and best i can tell with out a scope is my digital clock is keeping time this alone tells me the power is clean some inverts will make the time run slow and loose up to a hour or more a day. Power demands are working just fine and the voltage is 121 and holds there pretty well.Voltage Max verified 16 volts is the shut off for this inverter and 15.9 is ok to run.Why would i wont this voltage? Lithium-Ion 18650 cells. Yes finally an inverter that can handle 95% of the voltage that a 4S pack can have. Ive near doubled the capacity being able to almost fully charge the batteries and not fully charging means the cells will have a longer life only charging to 95% of max charge is fine with me. Most normal inverters will only allow up to 15.2 volts and they shut down for over voltage ive got one as a spare that shuts down at 15 volts which is totally useless for lithium-ion 4S.My set up for voltage range is:13 volts automatic fall back charge starts for low sun days1000 watts in solar with a not so conventional 20 amp buck converter CC-CV this must have a fan and more heat sink to run at 22 amp constant MAX or it will fail by over heating and exploding the caps on the board the inductor get incredibly HOT or one of the mosfets over heats and fails ive also had one of the traces on the board to a mosfet burn out and had to fix it and replace the mosfet. Folks ive burnt up over 10 of these to learn what works and what dont! Now ive had 2 of these working fine for the last several months one for fall back charge and one for solar charge.15.9 volts is the high voltage stop point which is much better than my old inverter at 15.2 volts shut down.

If I could give Giandel a 6 star review I would. I bought one of these 3000w inverters and it ran well for about 2 weeks, then quit. Amazon sent me a replacement. Installed this new one, turned on the microwave,it ran for 2 seconds then the inverter went into permanent overload. I connected an extension cord from a GFI outlet in the house and connected it to the power line running from inverter to the electrical panel in my RV. Turned on the microwave, ran for 2 seconds, then the GFI tripped. I figured I had a short in the power cord or the Automatic Transfer Switch behind the electrical panel. Dug out the ATS, opened it up and saw a number of burnt wires. It was 19 years old and had been used with an onboard generator, now discarded. I replaced the ATS and ran a new 8/3 power cord from the panel to the inverter. I contacted Giandel and asked if they had repair facilities that I could ship the inverter to and get it repaired at my cost. They answered right away, had me take a video of the OL alarm on the lcd, I included pictures of my installation and the wiring, they said they would look into it. 3 days later I got an email with a tracking number. They sent me another new 3000W inverter, no hassles, no haggling! I double checked the shore power lines and the new inverter line, all appliances worked well, verified with an in-line amp/watt meter. When the new inverter arrived, I installed it, held my breath and turned it on. It is working just like it should ! It ran my microwave, my A/C, ( not at the same time, I am still gunshy), the coffee pot, even a 1500 W electric heater without a problem. Hopefully, I have it all sorted out and with the great customer service from Elsa at Giandel I will enjoy my truck camper out in the boondocks.

The inverter is great. I love the look how well built it is and the way it functions. The fan didn't even kick on at 1500 watt loads and it ran 3000 watt loads with no problem. My one complaint would be these under sized 2 wires they give you. They got very hot running 2500 watt load for over an hour. Please supply 1 AWG cables which you recommend or non at all and drop the price a little so we can buy our own.

This is the 5th large inverter i have purchased. This unit comes well packed, is a solid performer and backed by i credible customer service. This should be your first choice in all electronic safe inverters.

This thing is garbage. Ive sent in 3 e-mails in a week and 5 phone calls. Still no word back. Amazon said I missed the return window by 6 hours. For the money you should NOT have to call tech support with a brand new piece of equipment that is SUPPOSED to and EXPECTED to work UNCONDITIONALLY. Why would anyone put the HMI in a place where you physically cannot see it unless you mount it on the wall 5 feet off the floor so you can read the fault. The Remote is junk. Great its green means its on. The green battery level tells me how full/empty my batteries are and then there is a Fault Light that's RED. No idea what the fault is. I cannot see the damn thing. the Piezo will not shut off that blasted BEEP ever second until you shut the power off because someone forgot to add a SILENCE BUTTON to the PIEZO. I Digress. Guess ill have to crawl back behind the counter move all my gear and see what the code is. Frustrating to say the least. Then you do an install and right out of the box it says OL, 0 Output, 12.7 V 0 Amps, 2400 Watts. All my calls fall upon def ears. Ill call Visa and see if they will be happy to make a fraudulent claim and get my money back for me?
