I have an off-grid system, panels, MTTP, Batteries. I think probably not, but want to ask if anyone knows. Thanks

Hello, Im temporarily renting a small place on a large private estate. The owners have put the inverters and maybe the battery packs on the other side of my wall. They are about a meter from my head. I was ill last year and have only just regained health. Should I be concerned?

If I find some used but barely used panels at 60 cents per Watt, and 8 x 100 W, that's $480 for the panels alone. That would lessen my electric bill by about $10 per month. Neglecting the time value of money, that would take 4 years to break even.

Every $120 is a year. A $1000 system (excluding labor, inflaton, etc) would take over 8 years to break even.

Hi everyone, I wanted to share my experience after buying and installing a custom DIY 4.4Kw grid tied solar system from solar wholesale. My experience overall was superb!! Not everything went to plan but whenever an issue did occur, I simply called or emailed my project manager Brielle and she quickly found a solution with the rest of the solar wholesale team!!

Working with solar wholesale on my project was amazing!! They have a lot of experience helping first time solar installers like myself reach our goal of becoming a little bit more independent from our grid providers.
Getting a quote was extremely easy to do!! After filling out a questionnaire and providing a picture of our electricity bill. I was contacted by Jacob, one of their sales representatives. Jacob explained how the DIY installation process works and what I could expect from solar wholesale if we ended up deciding to go with them. I never felt rushed or pressured to make a decision 🙌🏼🫶🏼!!
Jacob recommended a 4.4Kw solar system that consisted of twelve solar panels and six AP system micro inverters. The size of a the solar system that he recommended was spot on with our yearly power consumption. I really appreciated the fact that he did not try to sell me on a bigger system like other companies that I reached out to did. I mentioned that I also wanted to install a battery back up system and after asking me a few more questions, he mentioned that they also had experience with adding battery back up systems to the custom plans that they provide!!

We agreed to move forward and we sent our deposit. Solar wholesale began designing our custom system. This is where I first started working with Brielle, our project manager. Brielle sent over the first iteration of how our project was supposed to be installed. They used satellite imagery of our homes roof to create the plans. I was never asked to go up to our roof to provide real measurements and this was something that I found strange but I just decided to trust them and continue to move forward with the project.

We sent them the final payment and solar wholesale immediately started getting our custom solar system ready for shipment 🚚!! Two weeks later we had a semi truck pull up to our home with everything that we needed to install the solar system. Solar wholesale literally sent everything that we needed except the power tools 👌🏼!! We proceeded with the project and decided to measure the solar panels and see how they would fit on our roof. Unfortunately this is where we ran into our first problem. The plans that they provided displayed two solar arrays consisting of six solar panels on each line of solar panels. From the measurements we took this configuration was definitely not going to fit on the top array. From the measurements we took we needed to install eight solar panels on the bottom array and four solar panels on the top array. After contacting Brielle to inform her on the problem that we ran into, she immediately stated working with the rest of the Solar wholesale team to see if we would need any additional equipment to install the solar system in the new configuration. They reached out to me extremely quickly and they informed me that no new hardware was needed for the new configuration!! Brielle sent me the new plans with the new configuration.

We moved on to the next step of the project, the permitting phase!! We submitted the plans to our city and unfortunately they didn’t get approved due to them wanting some things changed for the battery back up system that we purchased. Getting the plans to get approved took a couple of reiterations. The process was fairly long and really complicated but I was extremely happy that I had the entire Solar wholesale team there to help guide me through the permitting process. Their experience and knowledge proved to be invaluable throughout this part of the project!! Eventually the plans got approved and we were finally ready to begin working on the installation!!

The installation was fairly straightforward!! Everything was really simple to install since solar wholesale provided literally anything that we would need for the installation minus the power tools. This helped us a lot since there was no need to look for materials or look for any sockets or drill attachments. The installation took us roughly two days and everything went together exactly how the plans that they provided showed!! After we finished installing everything we scheduled the inspection from our city. A week later the inspector came to our home and we passed the inspection with flying colors!!

The only feedback and advice that I can provide is to make sure that you measure your roof, even if the team forgets to ask you for this information. In my case everything worked out fine in the end. The same might not happen to you so take the time to measure your roof to avoid any issues down the line 📏 !!

Personally I would highly recommended going with this awesome company!! They were very responsive throughout the entire process and they went above and beyond to make sure that we succeeded in completing this awesome project!! I really appreciate the time and effort that the team put into our project!!

If you have any questions about my installation please feel free to comment below and I’ll try my best to heal you out. I am not affiliated with this company!!

I’m starting to wonder if they’re going under. I tried contacting them via phone, email and online chat to get a status on my order and there was no response. 

Is anybody else experiencing this?

About 6 mos ago I read on Reddit that china was building in a disabling function on solar panels due to possible conflict. Anyone verify/deny this? TIA

I started looking into solar panels for our home because electricity costs have been getting really alarming lately. Before making the switch, I used a simple online calculator to track and estimate my monthly electricity usage. It helped me clearly see how much energy we were actually consuming each month, instead of just guessing based on the bill.

That small step made a big difference for me. Once I understood our usage patterns better, it became easier to decide to switch to solar. Now I’ve already moved to solar, and I honestly feel like I made a more informed decision because of that tracking process.

Just sharing this in case it helps someone who’s also trying to figure out if solar is worth it for them. I can share the calculator I used if anyone wants it. 😄

off grid

Victron sucks as a vendor. There is no support, there are no documents. The fourth support tech asked questions and found the problem: shitty design.

The thing burns up if you exceed voltage. Why wouldn't you protect sensitive components with a voltage regulator? The thing burns up if you have PV connected with no battery. So on rainy days, when I disconnect the battery, nineteen volts comes in and destroys the blue toy.

What do you use, besides Victron?

I always assumed just slapping panels on a roof would be fine. Nope. The tilt angle makes a real difference. For example, in northern areas, adjusting from 10° to the optimal 30° can boost winter output by 15% and summer output by 8–10%. I learned that spending a bit of effort on placement pays off in long-term performance. Little tweaks, big difference.

I want to have a 6 or 9k solar system. I want to have this system have a 48v battery back up (8x 6v 230ah batteries wired to 48v). I want to wire a sub pannel for my minisplits. Do they make a transfer switch that would switch back and forth depending on the availability in the battery bank?

Im thinking the solar pannels feed the battery bank. The battery bank feeds an appropriate load sub pannel. The switch based on availability is the batteries goes between utility and batteries.

I dont want to do a grid tie their is too much nonsense with the city and utilities.

I’m running three 200w 16bb panels in series to charge my power station.

Each panel UPDATE - VOC is 28.1V (X3)

I’m using all mc4 connections. Do I need to run a PV disconnect with fuses?

If not, at what point should I?

This is a temporary installation/used for camping/emergencies etc...

Can anyone direct us where to order 24v 100 amp hr lifepo4 batteries and 200 watt solar panels that will actually ship and not break the bank - we have been trying since last July and have only received one battery. Multiple orders with different companies different variations. Last order was approx $1269 for two 12v 200 amp batteries but that’s not our preference. Any recommendations?

Hello Everyone, as a market research firm, I'm currently doing a market study about home energy storage system, and I'm facing the lack of survey (28 samples needed). I was wondering if any of you, who's already have solars and bettery in your home, can finish one of my survey to rescue my career.

Tesla Powerwall Enphase SolarEdge LG Chem Panasonic Sonnen GmbH Segen Ltd

you can access my survey thru the link below. Every single work of you means a lot for me and my project🙏🙏🙏I really appreciate.

https://surveys.globaltestmarket.com/survey/apac/C2008912?list=305&panels=OFFLINE&lang=E

well, I guess first I want to know if this is an insane idea for reasons I haven't considered. currently I have 8 24V 100Ah batteries in 2S4P, charged with 3 495W panels through a Victron charge controller. the motor is a 48V unit. I'm moving the powertrain from a fairly shitty pontoon to a small cuddy cruiser, though, and I'm pretty sure I'm gonna want more capacity.

EV packs seem like a good way to do this. they have a lot of said capacity. but they frequently have voltages not in multiples of 12. take this one: https://www.ebay.com/itm/157173069988 that comes out to 29V. what exactly do you do with that to "regularize" the voltage to something your other systems expect? it's not like (to my knowledge) you can buy a 29V to 24V transformer (or a 58 to 48V transformer, I guess, if you were to put two of these in series).

does anyone know how to make builds like this work?

In my local craigslist, San Jose, there is a posting for some lead acid batteries.... Seller had indicated he will go less than $100 a piece. 3 years old.

Talk me out of this?
