    Restore

    My local restore over prices most items and super over prices anything they perceive as collectable. It wasn't always like that, but changed when they hired a new manager. I finally got tired of seeing that and told them that I would no longer shop there and why. It's unfortunate because the...

    How long can you (and your family) survive if the grid went down for an extended period?

    Yea no your pipes would never fill up, BUT your neighbors at the bottom of the mountain will have their houses filled up with excrement from everybody living above them. That shit rolling down hill will find the path of least resistance and that will usually be someone else's toilets and drains.

    400 amp main panel recommendations? (Norcal, PG&E)

    My house was built with 2 x 200 amp panels and has worked very well for me when I decided to add solar. I shifted everything I needed that my modest solar system could handle to one panel and the other panel remains connected to the grid. The cost of installing enough solar to cover my whole...

    solar pergola on pavement, only weighted down

    There's one thing that may or may not be an issue and that is the possibility of the bricks sinking slightly into the asphalt. That is assuming when you say pavement it's made out of asphalt. I bring this up because asphalt does soften when heated so depending how warm it gets there and the...

    DIY Solar Water Heater

    I don't know if I should be inserting Amazon links on here but a simple Google search yielded an Amazon hit right at the top of the list. I just want to say that I understand the need to do as much as you can to save money, but if's there's anyway you can get a commercially made water heater...

    DIY Solar Water Heater

    Here in the states water heater thermostats are readily available and are simply held against the bare steel of the tank. The one for a single element water heater should work for your application. It's likely the same thermostat as the lower one on a dual element water heater and the...

    DIY Solar Water Heater

    I personally wouldn't do it because her in the states there's no need to plus it just adds more potential failure and safety issues. Are there no commercially available hot water heaters in the Philippines?

    DIY Solar Water Heater

    Actually I had forgotten about the solar water that I built about 25 tears ago. In this case I took a an electric water heater removed the insulation, painted it black and put it in wooden box with a glass top and pointed it towards the sun. I worked pretty good but didn't hold the heat very...

    DIY Solar Water Heater

    If your pump is going to be exposed to hot water it needs to be designed to tolerate the heat. When I was seriously considering installing a solar electric system I kicked around many ideas for heating water. But in the end I decided to scale up my system design to include using my standard...

    DIY Solar Water Heater

    I built a solar water heater for my swimming pool like that with irrigation pipes and it failed the first time water wasn't flowing through it when the sun was on it. The water boiled out and the pipe slightly melted. I didn't watch the video so I'm not sure if he used different pipe. I also...

    LG combo washer/dryer with heat pump/ventless -$2k.

    Out of the top 4 most commonly purchased I would rank them: 1. Whirlpool 2. GE 3. Samsung 4. LG I would also rank top load washers above front loaders.

    LG combo washer/dryer with heat pump/ventless -$2k.

    I wouldn't build or buy a heat pump dryer. I also wouldn't buy any new major appliances or vehicles for that matter. Every manufacturer in recent years has lowered their product quality and customer service. Add that on top of the complexity of the modern offerings of today and we often times...

    Any Growat SPF 3000TL LVM-24P Split-phase users?

    I've been running a pair of Growatt LVM 24ps in split phase for almost 3 years now. I had a problem with them within the first 5 weeks that was related to poor quality control. I was sent 2 new main boards under the warranty which took care of that problem. They aren't perfect and have a couple...

    Growatt SPF 3000TL LVM solar charging problems?

    I never had an issue mine when I changed from the default charge to a higher setting. So yours works fine as long as you have it set at default or less?

    Growatt SPF 3000TL LVM solar charging problems?

    It didn't cost me anything as it was under warranty. I only put a small part of the blame for the board being damaged on over paneling as I also had my battery charging maxed out along with a high amount of 120v/240v loads all of which added up to maxing out the mppt for most of the day. In...

    Mouse Chewed Inverter Data Wiring MPP Solar LV6548

    Had a large mama rat have babies in my attic. I trapped all her progeny but she was to wary to fall for any traps so I had to poison her. She died under the air handler in the attic and I couldn't get at where her corpse lay so it stunk up the bedroom that was just below her. Fortunately it was...

    Woke up to blank SCC and drained batteries, now won't charge

    It's probable you batteries weren't fully charged and/or your loads are to much for your batteries to fullfill overnight.

    San Diego Gas and Electric Moves to reduce PV payment for NEM 1 and 2 customers

    I lived in the San Diego area from 1984 until 2015 and always had SDG&E and I can remember when rates were around .05 cent a kilowatt hour with no transmission charges or any other additional charges. Closer to the beach most people didn't have a/c and most everybody used natural gas for...

    What kind of ink did you use? Most printer ink is not UV stabilized and will fade rather quickly when exposed to sunlight.

    Mouse Chewed Inverter Data Wiring MPP Solar LV6548

    I can't tell what size wire they are but going a little larger wouldn't hurt anything. As far as how I would repair them. I would remove each damaged wire and connector from the inverter and solder them back together on a bench with some shrink tubing slipped on each wire before soldering...

    Mouse Chewed Inverter Data Wiring MPP Solar LV6548

    Most if not all of them look reparable. If they're not chewed all the way through you can separate the wires from each other and tape up with a good quality electrical tape or use some shrink tape. If to much of the wire is chewed through but you have good sections of wire at both ends then you...

    How do Calif. Community Enegery Electric Generation Charges work with solar PV?

    I lived in the San Diego area for 30 years and left 10 years ago because I saw the writing on the wall. San Diego used to be a beautiful place to live in many so ways. In California it appears the merging of big business & Government is almost complete. The rest of the country is soon to follow.

    How long can you (and your family) survive if the grid went down for an extended period?

    Most of my power outages are pertty short in duration. The longest one I had was for 3 days due to a hurricane. The rest are 1 day or less. As it is my system provides at least 80% of my current needs and what the grid provides I could do without if I had to. In the spring or fall I could run...

    24V Growatt SPF 3000TL LVM stops using solar even when solar is available

    There is a minimum voltage the mppt needs to start charging again but shouldn't be an issue if your current set of panels were enough for you inverter to function before this extended outage. Also even if the inverter is off I believe the mppt charger will still charge the batteries. But some...

    Watts247 review? No contact info...

    In late 2020 I bought a pair of growatts from watts24/7 and within 2 months I had problems with both of them. Ian was great and had them diagnosed over email and was sent 2 new main boards for the both of them which got me back up and running sooner than sending them both back. After that I...
