    3 pin port on 150A watt meter

    I searched everywhere, but can't find an answer. Does anyone know what can be connected to the 3 pin port on these 150A watt meters? Is it possible to download data maybe and, if yes, how? Thanks

    150A meter not turning on from solar panel

    I got one of these 150A meters and tested it with the 12V adapter on the picture just to make sure it was working. The screen turns on instantly and displays the correct voltage. Surprisingly, when I try to use it with a 100W solar panel (where I measured about 18V with a multimeter), the meter...

    Can a microinverter be for too many watts

    If you want to start a plug & play system with just one 100W panel and add additional panels later, can you buy the 600-700W version of a microinverter such as this https://www.aliexpress.com/item/1005004310586095.html or would this be too much for just one 100W panel? Thanks

    Did I buy the wrong amperage for my controller

    I have one 100W flexible solar panel like this https://www.aliexpress.com/item/32895636796.html When I ordered a controller for it, I thought "Let's take the biggest amperage, so it will be ready if I add more panels in the future". So, I ordered the 100A version of this controller...

    Crimper for MC4

    Could someone let me know if I can use this crimper for MC4 connectors? If not, do I need another crimper altogether or can I just replace the teeth with one on the back of the package (2nd picture)? Thanks

    Critierias to look for in micro-inverters

    I bought 2 brand new 280W panels on a classified ads website for ridiculously cheap https://suministrosdelsol.com/en/paneles-solares-especiales/770-copy-of-transparent-solar-panel-almaden-m60-280w-monocrystalline.html and my plan is to make a plug & play kit out of them. Unfortunately, I don't...

    Alternative to microinverters

    I'm trying to figure out what it would take to replicate one of these "plug & play" kits if you have standard panels that don't come with built-in microinverters. What type of inverter do you need between the standard panels and the outdoor outlet to replicate what microinverters do? Thanks

    Total newbie question

    Could someone tell me what would happen if I connected a system like this: Solar panels -> Solar charge controller -> Pure sine AC inverter -> Outdoor plug socket on my porch There would be no battery involved, unless indispensable. It would just be a couple of hundreds of watts, nothing crazy...

    DIY plug & play 600W setup

    I'm planning to install a DIY "plug & play" system consisting of two 300W solar panels and an inverter to cover some of my electricity costs. I have two questions at this point: - If I want to add batteries to cover my night consumption as well, what size of batteries should I go for if my...

    Fully solar powered A/C for flat in building

    Hi all, OK, here is my project. I'd like to install a ~9000 BTU split A/C inverter for the flat on the pictures. That would require about 1KW As I want to avoid the energetical waste and environmental impact of 1KW, I'd like this to be entirely solar powered, in the most direct way possible...
