Tomorrow iam doing a video for YouTube on both my pectrons.and as soon as I can afford my 200 watt solar panles I will be doing another video on all of it..thank you Giddy up go Melody. Melody Johnson
These ten 560 watt panals made a nice addition to my current system. Waiting for clear skies to see how they really preform. They did good on a cloudy day.
SKU SGR-5KE 5000W - 48VDC - 120V -
10.24KWH - 6x 415 Watts Solar Panels
Setup was simple and straightforward. Followed the diagram for my system. Installation can be done with very basic electrical knowledge. This was a fun project seems to be good quality and performance. Batteries charge via generator for emergency backup. 6 panels pulling 2.2kw with 13a from 0% to 95% 4hrs. sunlight. This was a great investment. No more monthly bills.
Well, as you can see, it looks very nice. But the instructions hate to use the word sucks took it apart and put it together about four times before I finally got it right. I believe the instructions with four different unit. The instruction showed 3 shelves. Well, mine has 6 shelves instructions showed a lot of stuff different, but after I figured it out, after about 6 hours. It went together as a solid unit. I'm very happy with it.
I decided with early warning of a potential damaging winter weather to invest in a whole home battery backup system. The Anker Solix F3800 plus to include 400 watt solar panel and two expansion batteries and a tri-fuel gas generator. I still need to purchase and install the home smart panel which I’ll do before summer. Luckily I spent the time to cut down potentially damaging trees that may have been susceptible to icing, earlier last year.
Great quality switch. I did have to search youtube to make sure I wired it correctly. Once you understand how it works, it was pretty easy. Would buy again!
Very pleased with the performance of the system. Highly recommend Solar Guys Pro. Solar kit arrived fast and well packaged free from damage. Great communication as well.
Epoch 460Ah has massive reserve power compared to two deep cycle lead acid batteries. Very happy with my purchase. I also fixed the clutter from the factory power distribution and added a plexiglass cover to be able to see it all.
Love the Sun Gold it is fantastic. Do not be fooled by the look alsikes. They look like they were made on the same assembly line with just different paint. I have Eco worthy and they give me problems one of them is a daily issue to get it to start charging. Sun Gold never fails. All my Sun Gold hybrids never have issues so far. I also have a POWMR it turns off and on in the after noon constantle error codes 1,3, and 4 but I have been through the recommendations to fix the issues but still have the same problem. Do NOT stray away from buying the Sun Gold . The service guys here are great. They might be busy but they will get back with you pretty fast. From now on this is my one and only place to buy solr products.
I am a 70 year old disabled Vietnam vet. Every bit of the installation was done by me so good or bad it is mine. These inverters have their challenges but everything here was done in about 40 hours total. The wiring is very straight forward and the programming will make you scratch your head. SOLAR GUYS PRO and SUNGOLD technicians got on the phone with me and in 15 minutes my system was working properly and doing a very good job. 3300 watts total incoming solar landing on 12 total 12.8V 100AH batteries that are wired as Parallel Series to give 3 banks of 48 volt,100 Amp hour connections. Simplistic in operation but strong at the same time. If anyone wants to know the settings I use just ask.. Thank you Solar Guys. Michael
Dual battery setup with my Iceco APL 35 worked great. Temperatures were consistent on a five day trip to hot and muggy Tennessee. Li Time battery never went down below 90%. 200 watt Rich Solar panel mounted on the tonneau topper kept the lithium battery charged. For further insulation and protection, I wrapped the Iceco fridge with Reflective Insulation. My wife and I are delighted with this cooler. No more ice needed on our month long tent camping trips.
200w solar panel is great power i will never use all 1056wh from this anker power bank while I'm charging my familys phones and tablets even on a cloudy day. I got this to charge my e-bike and it will fully charge my 21amp hour e-bike battery great purchase anker is the only brand I'll purchase check out all there speed charging cables and batteries and solar guys saved me $100 over any other website buy Anker from Solar Guys
Keeps my house powered all night, only use 50% of battery next day by 10am its back at 100%. Left space for 2nd battery for the near future. Hoping to get it soon so I can do some EV charging at night.
In March this year (2025) I had a Epoch 12300A-H Essential Battery installed to replace my four older Trojan T-105 6 volt batteries. The Epoch had more capacity than the combined Trojans which surprised me. I like the performance and really liked the Epoch app which made monitoring the battery conditions very easy. After experiencing the Epoch performance for 2 months and discussing with my wife we decided to purchase a second Epoch 12300A-H to install in parallel with the first one. We are pleased with the extra capacity we now have and really liked how the Epoch app linked the 2 batteries together. Our 570 watt solar system will also do a good job of keeping these batteries up for more RVing adventures.
Installed in Monaco Diplomat Class A, diesel pusher, motohome.
I put this on my cargo trailer to power my portable freezers. I go fishing for five months and some times I’m in remote locations so being self sufficient is essential. I have been running the freezers for a few days now and they haven’t even put a dent in the power, batteries stay fully charged.
Relatively easy plug and play Install. Took us all day to finish, making sure our panel layout would work with 50 yr old trusses underneath. Will purchase again.
