Y&H 3200W Solar Hybrid Inverter DC24V to AC230V,Off-Grid Pure Sine Wave Inverter with 80A MPPT Solar Charger+AC Charger,Max PV 3000W DC55-450V Input,fit for 24V Lead-Acid/Lithium Battery

First time I bought this unit I was impressed by its clean look and its design. I have 4X327=1,308.00 watts of Solar Panel in series and parallel connection giving me about 120 VDC for my PV input. I’m using it for my Off Grid System since it’s not compatible with (Edison) 2 phase 240 VAC. The idea is to power my mini split type air-condition to save cost from electric bill. I sit down/observe on weekend before decided to leave it alone for week days. It works great but not perfect, had some issues like warm to the touch above the displayed screen, it draw a lot juice from my battery's. Really not an issue if I have massive amount of battery bank. Few days before the 30 days return policy my battery dc circuit breaker side (63amp) trips and almost keep doing it on a regular basis. The last 2 days of the return policy I notice that my indoor unit air-con blower fan acting up like on/off continuously. I check my controller and I notice my VAC output giving me 230V then 0 and so on. That Sunday night decided to return my unit the next day 08/14/23 thinking of getting another brand probably cost more $ but with quality and good reviews online but ended me giving another try for this unit. Fortunately! I received the replacement unit yesterday 08/16/23 kudos! for that. I Installed last night hopefully! never had any issue again. For now I will give a 3 star until it proves this unit is worth to keep. Will giving you more update since I have another 29 days to observes. 2nd Update 09/16/23 After 30 days observation I did some minor tweak/upgrade with my system. I replaced my (2) 12V 100Ah with (1) 24V 200Ah battery and 63A-100A DC Circuit Breaker but can handle 125A based on stickers behind the unit and the rest are history. It’s worth ($) to invest more aesthetic it’s like 2 or 3 in 1 unit instead of having 2 or 3 unit hanging on the wall. The display itself gives you more than enough details/data of what is going on with inverter. I don’t have any more negative things to say about this unit and I’m hoping will last several years of usage and I’ll give this inverter unit 5 Star…

I have used this with a 2000w solar system for about 6 months now. I have had no problems at all with it once I took the time to learn to use the menus to set it up. I wired it up to plug into a 220 wall socket so, on AC or solar it can charge a 200AH LIPO4 battery at 57A with no issues. In Off Grid Mode, it turns on and off whenever there is any power coming in from the solar panels. The cooling fan adjusts automatically up or down depending on how many amps it is charging. I get 110V out of it two different ways. I have a 110V inverter hooked up to the battery. I also hooked up a stepdown transformer to the output of the Y&N controller. When the street lights come on in the evening, this controller is still processing power from the solar panels. Yes, it's only a few amps, but it's almost dark. When it does finally get dark, the controller will shut off if it is just in charge, and not inverter mode. I am pleased with it so far.

Update: Support response was. "Thank you for contacting us for Y&H after-sales support. Please disconnect all connections and use the battery to connect the inverter separately. (The battery must be fully charged) If it is still a travel error 09, then the motherboard needs to be replaced." I had tried sending a response twice and no response, so I guess im now ghosted. Uploading a photo of the motherboard where the parts ended up frying, and was only running 13 amps when it happened. System failed after 5 months of good use I got surprised with error code 09 - BUS Soft Start Failed / Internal Components Failed. In addition, the systems voltage meter reads 0.2 volts over the actual double-confirmed voltage, meaning you might not get a complete charge. As I'm outside of the return window so I am contacting their vendor support via their website to see if they can help. I will update if I get a satisfactory resolution. Still a shame about the reliability so you should have a backup replacement system ready to step in or be okay with this system going down and being without power for a while. But then again, what do you expect with something relatively cheap for what you get. Still, it's nice to have the option to charge batteries via AC. I am currently confogured for Off-Grid so I haven't tried the redundancy setup with solar priority or AC priority, but I'm assuming those would work.

Installed on a 200AH lithium battery being charged on a 12V solar 4 x 150-Watt array with a separate charge controller. So far, 1100-Watt microwave and 1000Watt pressing iron are working very well. happy lndeed

Estoy muy complacido con este inversor, es eficiente, práctico y muy fácil de peogramar.

no funciono y no me da opcion de devolverlo,
