Review on Y&H Grid Tie Inverter 600W Stackable DCDC15-28V PV Input AC110V MPPT Pure Sine Wave Micro Inverter for 12V Solar Panel/24V Battery by Paul Philippe

First of all, I was disappointed that this inverter only works with a 24V battery, at least. It cannot be made to run on a 12V battery, although this limitation appears to be a firmware limitation and not a hardware limitation. I bought it to use with my Model 3 to export power from a 12v PC (capable and tested at 2200w continuous at 12v). But no. It only puts out about 150W when using 12VDC (actually 13.5V). So I switched it, setting the lead block to 24V just to play around with it. This worked, but after a brief starting peak of 630 watts, it only produced 550 watts of continuous power. Who ran twice for an hour and a half. From the third time my garage started filling up with smoke. As it turns out, along with the impressively TERRIBLE banana input they use (instead of the screw terminals that every respectable inverter uses, those banana nuts can't be removed to mount a ring terminal), the factory hasn't even tightened the inside ring terminals onto banana pins . So he tried to melt. Luckily I caught it in time, but it's just one thing. really eats up my patience. With as good a design as it gets, they've really messed up some simple things. I've also had no helpful replies from support regarding the 12 volt thing. I asked twice if they had a product that could run on a 12 volt battery and each time they evaded the answer. Without worrying about supporting it. I'll fix it myself 🙄Update in a few months: I've replaced their awful banana clamps with an XT60 plug and continue to use this inverter every day to time shift the output of my solar panel (it's a 2*36V panel , either in series or parallel and immediately out of OCV range) to discharge from a 24V battery during peak periods. It's really annoying that I can't set the cut off voltage (so it stops working and doesn't just drop off it seems) - you have to schedule it manually and switch from using a smart plug and monitor the voltage every day, but it works. He does what I need.
