Y&H 700W Grid Tie Inverter for 24V 36V Solar Panel
This 700W Grid Tie Micro inverter is a compact unit,which directly converts direct current into alternating current.
Multiple panels are connected in parallel or series, and must have the same specifications for voltage and power.
• Use solar panel ONLY connect to this equipment. The AC output must be connected to the home grid.
• Solar panel open circuit voltage ≤46V (Voc), Solar panel power cannot exceed 700W
• The positive and negative poles of the solar panel cannot be reversed.
Vmp=working voltage; Voc=open circuit voltage. 50V working voltage input cannot be used. (Vmp)
Please use 36V solar panels. Open circuit voltage 38-46V (Voc)

arrived on time, works well. you'll get about 75% of your panel's rating into the wall with this inverter. For instance, one 100 watt panel will get you 75 watts in full sun. It takes around 25 watts from the panel to kick the 12 volts d.c. up to 120 volts a.c. Two 100 watt panels will get you around 150 watts into the wall, and on and so forth.It will definitely turn off if you exceed 50 volts input and not output anything. It also is more efficient with higher voltages. I have my 6 100 watt panels configured to get close to the 50 volt limit but not exceed it. With 6 panels I'm getting 380 watts into the wall.At 13.5 cents a kilowatt I figure 4 years for breakeven on panels and inverter...Unless inflation doubles the price of energy soon in which case 2 years to breakeven. Nah, the main purpose of this for me is to augment the output of my off grid backup system in a grid down situation and save a few clams on the electric bill in the meantime.

I have it wired correctly and connected to two 12v solar panels in series. Light turns green indicating that it's working, sensing utility power and accepting the solar power levels. I have two power monitors and neither of them indicate any current being generated.(It makes a very slight sizzling sound but does not seem to get warm.)

Works as intended for me, even off just one 12v 100w solar panel. The only thing ive noticed is when output is low (dawn/dusk) and the inverter is putting out 5 watts or less, it starts to make an audible buzzing noise. Its not loud, just noticeable. It shuts off when AC is lost, so no worries about harming line workers. When reaching high output to near its rated, it does get hot but the heat ive seen on mine is acceptable. I have the 700W version, seems like people have more heat issues with the 300W model. Its also built quite sturdy, case is strong and well designed. Better than I was expecting, now lets see how long it will last..

My project: I have two of these connected through a 48V 20A (960W) buck converter attached to a pair of 100AH 25.6V LiFePO4 batteries (5kWh). The buck converter provides a nice, smooth 48V no matter the input voltage, so it keeps both inverters running at around 330W each. This power is provided in place of solar panels; it's like having a constant solar output for however long the batteries last. I attached standard NEMA 5-15 plugs on each inverter, and plug them into a couple of smart plugs (Wyze), so I can schedule them to turn off and on. Unlike an off-grid inverter, when there is no AC power detected, these inverters do not draw any DC power either. Using this setup, I am able to time-shift my energy use for my house during peak electricity cost (4-9pm). The batteries charge up during the day on solar power using a normal MPPT charger, and then provide about 660W of electricity back into the house during the evening, offsetting the majority of my base load.I have done three things to make sure this does not go badly.#1 I bought some aluminum heat sinks approximately the same size as the inverters and attached them directly to the outer casing of the inverters with thermal adhesive tape.#2 I have a 24V fan blowing air across both inverters constantly.#3 I keep the inverters indoors. They are mounted in a box in my garage, away from anything flammable. So far the highest temperature I've measured in the uninsulated garage during this experiment is 83°F. As summer approaches, and I start seeing the garage get hotter, I will not be surprised if these things can't cope.Between these mitigations, the inverters so far have not heated up enough to burn my skin. They do get mildly warm, and are nice to warm my hands on if I am working in the cold garage, but this has been working every day for the past 4 months, and I have so far seen no degradation in power output.These things are cheap, both in price and quality, and this is a huge experiment, but so far it seems like it's working out well. If I get a full year of use out of these inverters in this unsanctioned manner, I'll consider that a success.Unless you really know what you are doing, I do not recommend you try this yourself. Except the attaching of heat sinks with thermal tape, and cooling them with an external fan. I highly recommend that for extending the life of these inverters.

Works as expected. Connect it to an outlet, and connect solar to it. It gets warm, even when not in use (which makes me think this unit consumes power when not in use).A thing to note is that the voltage range is very narrow, and the device will not work outside that range (above or below).

Was running six 100 watt panels. at first it was working good putting out what was expected. did run a little hot though. power efficiency was at 79%-85% ran like this for about a month then it started getting hotter and the efficiency went down to like 50% then I came out and the red light was on and it hasn't worked since. Smells like it burnt

It was pretty nice while it lasted, died just short of a year.

It works cooler if you dont use it at 300 watts . At150 to 60 watts it works great . It does work but at 300 watts it gets very hot. So this thing is going to get up to 150 degrees F every day
