This review is for 3 ECO-WORTHY products that I ordered at once for my off-grid tiny home/cabin.- ECO-WORTHY 400W Solar Kit with All-in-one Inverter- ECO-WORTHY 400W Wind Turbine Power Kit- ECO-WORTHY Water-PumpAs a novice in off-grid living, I have now learned this was a huge and costly mistake to have put all my eggs in the ECO-WORTHY basket.1- Tech/Customer Support: They are EXTREMELY difficult to reach. There is only 1or 2 reps for the whole company. It took me 2 days of repeatedly calling to finally get someone.2- THE PRODUCTS ARE NOT GOOD QUALITYa- For the 400 W SOLAR KIT WITH ALL-IN-ONE INVERTER, even with 4X 50 Amp Batteries, the 24 V 1500W inverter doesn't charge the batteries enough to keep working thru the night, even though I am located in the Caribbean with constant sunshine throughout the day and have no obstructions or trees to the panels watsoever. All Im running is a small fridge, and laptop charger and a wifi router. It also makes a really LOUD AND ANNOYING BEEPING sound when the batteries are low, so you have no other choice but to get out of bed to shut it down. My neighbor lent me an 12 V 800W Victron Inverter to help me out, and with the same 400W panels and 4 batteries, it got me through the night with no problem.b- I then bought the 400W WIND TURBINE thinking it would help keep my batteries charged at night since I am located on a hill facing the ocean and I have a lot of constant wind. FIRST OF ALL, the instruction manual for this product is probably the WORST I HAVE EVER SEEN for any product. So you better know what you are doing, because as I mentioned earlier, tech support can't be reached easily. But even after somehow succeeding in installing it, the blades don't turn quickly enough even when faced with very strong gusts of wind. So once again I am faced with another ECO-WORTHY DUD.c- The DEEP WELL WATER PUMP. BEWARE!! Even though it is sold as a kit with just one 100W solar panel, IT WILL NOT WORK! You need at least 2 X 100W panels in order for it to work. Also, be aware that there is no OFF/ON switch. The only way to turn it off is to disconnect the cable from the panel. If you need the panel to work at night, you'll need to connect it to a battery.In conclusion, I regretfully will no longer purchase ANYTHING from this company or brand. I will instead go for more reputable brands even if the prices are higher.I purchased this for son trying to homestead in a camper. Solar panels keep his batteries charged good. The wind turbine needs heavy wind to move. During storms when no sunlight is available the turbine kicks in. We have 5 batteries and they have not run out in the last few months. Afternoon storms in the mountains keep turbine movingThis wind generator is garbage do not buy… Yes it was set up right before I took it down I get wind strong enough here to up root tents and I still have not seen this thing spin. However, the solar panels are amazing and the charge controllers are decent as well that is why I provided a few extra stars.I must say for this being my first solar wind power system it was a delight to install shipping was really fast but of course I am already in southern California would I buy from them again you bet I would. BUT there are some things that buyers should know before buying one of there systems first you don't get no tools to tight the screws down you don't get no wire but that's a given of course the instructions book is kind of useless better off to use their site for info still haven't found out what the work modes do just yet other then that it works great charges the one 109 amh deep cycle battery pretty fast light on controler do their job. All in all great purchase thanks michaelPanels and turbine work great .... Controller is garbage. Had to trash it and buy another one. Worst instructions ive every seen.works great and does very well keeping the batteries charged up on days of low sun.I use this to power an amateur radio repeater in an old fire lookout at 6000 feet. High winds and heavy snows this winter had me worried it would not be able to last. But we put it up in November and here in March it is still working. I got to where I could see it from below through a spotting scope (snow too deep to visit it) and the turbine is still turning and the panel is still there. As the site gets a fair amount of use and power draw, it clearly is keeping our battery charged.i have it up not all wired in yet , looks good lol
