    Is your problem resolved? Looking at the picture it looks like you don't have the negative cable from the battery to the inverter connected.

    Best solar Panel output, mounted verticaly on a wall facing south in Cornwall UK or flat horizontal on a flat roof

    Hi. I live in Washington state Close to the 49 parallel, We get plenty of sun in the summer. You can even put panels on a north facing roof and they will work. However in the winter it is another story. You have to place your panels to squeeze all the energy you can from those limited winter...

    I looked at the SolArk and the one that would handle my situation was way too expensive. I think I am going to refigure my PV strings. The only way to get anything close to a balance is to have four strings of six panels in series with 210 volts at 9 amps. Then combine two of those groups in...

    The string of 2835 watts is made of three series strings. Each one has three 410, watt panels to give 105 volts at 9 amps. Those three tied in parallel will give me 105 volts at 27 amps. I decided to go panels first so I could work on mounting them, while I gained knowledge about the BOS...

    The 2 strings @2520 watts each are set up to minimize the effects of shading in the winter months when the sun is low in the sky and casts long shadows. My third string of, 2835 watts, does not have shading issues. If I tie strings (1) and (2) in parallel that will bring the amps of that...

    Can you clarify about the loss of production from the larger string in earlier post? If I get three separate charge controllers for my three strings, will I also need three inverters? My ultimate goal is to get 240 ac to electrical panel.

    I live at the 48th parallel and in a valley to boot. During the summer months I lose direct sun around 3 or 4 p.m. , so I don't think the loss of panel efficiency due to high temps will be too drastic.. Conversely in winter months, if I received more panel output due to lower temps it would be...

    thanks for the response. here's my question (s) does each panel need its own mppt device? Can strings of panels have their own mppt ? can three strings with different wattages use a single mppt device ? i.e. String (1) 2520 watts, string (2) 2520 watts, string (3) 2835 watts. I am...

    Hello, I am new to using a forum as an informational tool. I don't do social media of any kind. I think most of you assume that if a person finds this site you must know how to post . There are no real instructions or examples to guide me. I have made two posts and can find neither of them...

    Solar newbie post - 32kw off-grid solar diagram, can anyone review?

    Hi, I am new to the forum and are doing something similar to you only on a much, much, much smaller scale. Did you account for the 75% rule when sizing the panels or number of them? I am using 410 watt panels but only expect to get 307.5 watts out of them.

    Using S-5! with tilt rack?

    hello I too am in the same situation. I need to tilt most of my panel at 48 degrees and a balance at 18 degrees since another on a roof that has a 3o degree slope. I have gone to the s-5 web site but haven't got a response
