⚡️ ECO-WORTHY 4 String PV Combiner Box: Lightning Arreste, 10A Fuse & Circuit Breakers for Solar Panel System Review

I used this to install 24v for 8-100w panels arranged in 2 rows of 4 panels in series/parallel. Everything was working fine and on the 5th day it just stopped working. The charge controller is no longer charging my battery at 24V. I checked the system and found that the PV Combiner Box was supplying less than 14V to the charge controller despite the correct input voltage from the solar array. I bought it as "Used: Very Good" but it turned out to be "Used: Not Good". That's $100.93 not including

This is the second combiner unit I've bought, the other was a 6 string eco friendly. The box looks good but check the mc4 connectors as they use cheap ones that don't snap properly so you may have loose connections or no connections at all. I noticed that the 6 string I was using had loose connections, had to replace the single row mc4 connectors and push down while inserting another to keep the connection for a couple of days. I lost half my strength, it confused me a bit until I figured it…

Impressed at first. I have 1 array but I selected this block to expand in the future. Purchased January 2021, installed February with 1 input array. May 2021, box fuse blows. I thought it happened. My panel connection has been moved to the next group of inputs. Burns out after 1 month. I switched back to the 3rd set of inputs, blew through in less than a week, and finally blew through the last set in less than a month. I took the combine off, put in the built in fuse and there haven't been any…

Very good for connecting multiple solar panels. This is much better than 2-pin and 3-pin connectors, especially if your panels are high powered. People should be aware that each MC4 connector (pair) is rated for 30 amps. Multiple high power panels are connected to the same MC4 connector and may exceed its power rating. With such a junction box, each panel gets its own fuse connection, which is connected to a common heavy-duty circuit breaker. It's much safer. It also makes it very easy to…

I don't know where the bad reviews are coming from. Some are so dumb as to say the terminal covers aren't tight. We will have an ingenious channel blocker. This item is well made and works great with my 6 panel 1kW 24v system. Equipped with wiring and very easy to install if your IQ is over 100. 4 stars because: (a) there are no instructions other than online and they are conflicting, conflicting pictures and wording (e.g. pictures showing which + and - lines are reversed); and (b) customer…

I am currently working with 1-4 strings and 1-6 strings. I am very happy with both. I didn't get a 6 string key and never gotten a missing key response from the seller/manufacturer, but any 5 year old can pick a lock in 30 seconds and an old Pontiac key is perfect. fit. Both devices have been working for about 2 months without any problems. All connections are normal, the voltage is stable. The build and wiring quality seems to be as good or better than most other brands. I will buy another…
