    No controllers with WiFi and Android phone app?

    I have been looking, but no luck. My solar-powered garage has a Liftmaster opener that I monitor and control with my phone. The same with my HVAC thermostat. Even my washing machine and range have apps for controlling them (not that I would bother.) But I still have to run out to the garage...

    Is it okay to completely discharge LiFePO4 ?

    I did look for an answer here, but no luck. A friend of mine has a Bluetti setup and said that they recommend completely discharging them every few months. That doesn't sound right to me. Here is what they say. Notice that they don't say to completely discharge them, but is that what they are...

    WiFi Controller

    I have an off-grid system that powers my garage, which is around 30 feet from the house. I'd like to get an MPPT Wi-Fi controller that I can monitor from inside the house. Can anyone recommend one? Thanks.

    Does Will Use an Off-Grid System?

    I saw a video a while back in which he had a grid-tied system for his Las Vegas house. I was surprised that it wasn't off-grid. Any thoughts on why that's the case? Or maybe things have changed or I got it wrong.

    What if just a small part of my panels are covered with snow?

    I have four panels on my garage roof hooked up in parallel. It snow last night, and I took a broom and cleared most of it, but I couldn't easily reach the vey tops of them. In bright sun I only was getting .3 watts. I then got a bigger ladder and cleared the top 3 inches and I am back at full...

    Sloppy External Wiring

    I have four panels with two sets of wires. The panels are about 2" above the the wire junctions. We covered them the silicone, but I know that's not a good way to go. Should I put some kind of flashing over them, or should we lower the panels to cover them?

    Battery Drawdown Question

    I have power 100-watt panels driving an MPPT charge controller and four 100Ah batteries. I know that I can only draw them down to 50%, which is 12.2V. The display on the SCC shows that current battery voltage, so I have been going by that. It doesn't take too much to get down to 12.2. I...

    Grounding Necessary?

    I have a detached garage and I recently threw four 100W panels on the roof (in parallel). They connect to a 30A MPPT controller, four 100Ah batteries and a PSW inverter. Everything is fused. I am concerned about grounding. Any suggestions? Thanks.

    Are all of my four panels working?

    I installed four 100W panels in parallel, which feed an MPPT inverter. I am getting around 8 amps at midday. I think it should be a lot higher. I have two branch connectors just above the controller inline fuse. One has two negative cables and one has two positive. As a test I removed one of...

    Branch Connector Location?

    I now have four PVs on my garage roof and am going to wire them up today in parallel. (I had one PV in place already with two batteries. I now have four batteries, so the one 100W panel is doing all the heavy lifting.) As the one PV was already in place with its own hole, we drilled another...

    Three Epever Questions

    I have a 30A Epever MPPT controller that I have just installed, and I can't figure out three things. I should mention that there is no load. The controller output is only connected to the battery bank. 1. How do I know when the battery charging has stopped? Does the moving arrow between...

    Renogy vs. Epever LCD display

    I really don't like the blue lit display on the Epever. The Renogy devices look like they have an easier to read LCD panel. Any thoughts on that?

    Will this work?

    I bought an Epever 30A MPPT controller for a four 100W panels. I considered the input amperage but not the input wattage. The max input is 390W. I know the that the panels aren't 100% efficient. Will this work, or am I too close to the limit?

    Low Voltage Cutoff Question

    I have a simple 12V system with a 100W PV and two 100Ah AGM batteries. I am under the impression that I shouldn't ever let the batteries drop below 12.2 volts - 50%. I see that the charge controller (Windy Nation P30L) was set to shutdown at 10.7V. If it hits that, wouldn't it be too late...

    Perfectly Balanced Charging

    I see a diagram that shows what perfectly balanced charging looks like. But it only shows where the charge controller gets attached. Where to the battery cables attach? (*Click on the photo).

    How Many Fuses For 4 Batteries?

    I have one battery and a fuse located between the battery and the controller, PV and controller, and between the battery and the inverter. Should I add bolt-on fuses for each new battery?

    Confusion About Charging and Controller Power

    I have a 100Ah (1200 watt hours) 12-volt battery and a 100W 12-volt panel, and here is what I came up with: At full sunlight it would be delivering around 5-6 amps or (50-60 watts) to the battery. I know I shouldn't go below 12.2 volts - 50% of the capacity. Where I run into problems is with...

    Dumb Question About Battery Monitors and Shunts

    I have read that shunts are used to monitor the state of charge for batteries. If that's correct, what is a battery monitor for? I see that they are sold together. I have searched this subject but just find it more confusing. Can anyone clear this up? Thanks.

    Too-fast AGM Drawdown?

    I know very little about solar, so if I am asking some dumb stuff here, that's why. I have a 12V system that was installed 10 months ago for a detached garage. I have a Windy Nation P30L charge controller, two 100Ah AGM batteries, one 100W PV, and a 1500W PSW inverter. So if I draw down to...

    Do I need a better controller?

    I have a 100W panel, 12V system, two 100Ah batteries, and a P30L 30A PWM controller. I am going to upgrade by adding three 100W panels for a total of four, and I will add 2 more batteries for a total of four. I think I need to beef up the controller. The vendor says that I don't have to, but...

    Detached Garage Solar Expansion Planning

    I am new at this, so forgive my lack of knowledge. My garage is about 35 feet from my back door. Last summer I wanted to make the garage powered by an off-grid system. It works great. I have one 100W (monocrystalline) PV on the roof, a 30A PWM charge controller, and two 100Ah AGM batteries...

    Where is the DIY Video?

    Will was going to post one for solar generators after he did this one. Does anyone know where it is? Others have asked, also. I'd love to see the follow-up! Update: I can't delete my post, but I did find this:

    Off-Grid Advice Needed

    A friend of mine who lives in the Colorado mountains was thinking about installing a grid-tied system, but it was too expensive. Instead, he wants something for emergency power only - to run a water pump, refrigerator, some lights, and maybe a microwave oven. He looked at a 7200 watt-hour...

    Off-Grid Charge Rate and Will's "Electricity Explained" video.

    Two situations here. I recently decided to power a detached garage with an off-grid Windy Nation system. A 100W PV, 30A controller, 1500W PSW inverter, and two 100AH lead acid batteries. (Great service and support from the vendor). The system powers the opener and a few lights. For fun, I...

    China vs. America YouTube Video and Will

    Wow! I am fairly new to Will's channel and I watched the video mentioned above the other day and agreed 100%. That was excellent - Will really nailed it and it needed to be said. I really don't understand who would downvote something like that, except for the very kind of people he was...

    Charging Stopped

    I have a 100W PV attached to a Windy Nation P30L charge controller, a 1500W pure sine wave inverter, and a 100ah battery. The setup is a month old. It's been mostly working well, but every now and then charging stops. I'll then jiggle and tighten the fuse assembly and wiring a little and it...

    Is there a way to track and quantify solar output (off-grid)?

    I recently installed a simple system for a detached garage. (I didn't do it to save money). It powers the opener and two LED lights. I did this project as an experiment in order to learn about solar and how it works. Again, this is not about money. As it is summer, I have the back door of...

    Off-Grid Garage System Question

    I have a detached garage and I would like to power the Liftmaster opener with a solar power system. It uses 540 watts (120 volts), so I am guessing I need a 600-watt system. But do I need that much power for something that is only used 2 or 3 times per day, for about 30 seconds total? Also...
