Been using a Johnson 64534 Washdown Pump 12v 5.2gpm to pressurize our bladder pressure tank at 70 PSI for the last 13 years. Works great!!!

We have been cooling a 2000 sq ft home for the last 20 years with a single window a/c for the last 20 years. It gets to 100F here in the summer. We have it mounted near the ceiling upstairs. We have an open floorplan upstairs.

Do you have any wind power? This would be interesting to see how the system would react with wind added to the mix.

Small tank Larger Tank these are usually available locally up to 120 gallons. Washdown Pump This pump has a built in pressure switch and an easy clean inlet screen. I have been very happy with it's performance and longevity. The pump usually turns on about once a weekend. This depends on...

I use a 12v washdown pump that puts out 5+ GPM at 70 PSI with a pressure tank to keep the pump from turning off and on all the time. I use a small tank on my trailer and a 80 gallon tank on my off grid cabin. Both pumps have lasted 10+ years.

Ran across this review from a Costco customer who purchased. ★★★★★ 1 out of 5 stars. · 2 years ago False Advertising Costco and Massimo website advertise the cooler as having a LG Compressor but I can see from the vent of the cooler that...

Wiring diagram would be awesome

Do you have cellular service where the unit is located? I have a possible solution if you can get an internet connection.

I currently have a DIY transfer switch between my 120v Inverter and 120v generator using one of these. It has worked good for my application. I am changing to a new generator that produces 240v along with a new breaker box that can accommodate the 240v. I need help figuring out how to make a...

I have been running a Morningstar Mppt for about 12 years now without a burp. They have very low operating consumption and very high reliability.

Did you ever get an answer? Mine have the UART and RS485 plugs. I was hoping to monitor all 4 BMS's remotely via internet. Using a raspberry

Google does not find RECOM R-28E5.0-0.5

Wondering if it is a Firmware issue. What firmware version are, those that are having a problem, running?

There are lots of little Chinese components that can fail in that electronic device vs a thermo-mechanical device that has decades of dependability under its hood. I like, not depending on relays, 10k sensors and circuit boards put together by 10 year old children. I know I can't avoid...

It has a NO and NC set of contacts.

I like simple and I like reliable. That's why I went with a solution that requires zero energy while monitoring and energizing the temperature control. I have found that the silicone heating pads kick out an amazing amount of heat, rather quickly.

This project is right in line with what I want for my off-grid location. I honestly have little experience with the raspberry pi but can figure out just about anything with a bit of detailed instruction. my system has the following. 1- Morningstart 45A Tristar MPPT SCC 1- Morningstar Relay...

You need to set your solar charge controller and line voltage charger up to work with your BMS settings. I set my SCC and line voltage charger to operate just below the BMS thresholds.

I'm from the school of "Better to have it and not need it, than to need it and not have it." This is why I have backup components in cardboard boxes, inside metal boxes, inside metal containers. I have Midnite Solar lightning protection on my solar combiner box as a minimum protection. I...

MidNite Solar's Surge Protection Comparison Test Good video on lightning protection.

I am considering using a Victron Energy BMV-712 as my Generators Auto Start control for when my batteries get low in the winter months. My generator has a simple 2 wire N.O. connection to initiate its self start sequence. I was going to use this Voltage Protection Module but I'm concerned with...

Again, it doesn't matter if the wire is connected to the positive or negative on the bus bar. It is just a matter of preference. Pretend the - & + aren't on the battery post in the drawing.

Just a heads up for anyone considering the Epever BN. Newpowa is selling the exact same SCC with their name on it for less. Comes with the same 2yr warranty. I picked one up for $156 here.

Morningstar has a 600v version of the Tristar MTTP

Those numbers you are getting are what you will get if the -B is not connected to ground.

I'm running 4 x 12v batteries with 4 x 120A BMS and a 12v 2000 watt inverter. More is better. :p Looking forward to running the Bosch Dishwasher this summer. Now if the snow will just melt so we can get to the cabin and hook these juice boxes up.

Was just looking at your photo. Connect at least one of the -B wires on the BMS to the negative post of your battery. Your BMS will not work properly without the -B connected.....I know from experience.

Sounds like you are in a pickle. This guy can't ship until April 9, but he is in the USA. It is basicly the same unit.

I built my own system for less than $150. It calls me if the alarm is activated and turns all the cameras on. My neighbor is closer than the sheriff and has permission to shoot anyone who comes down my road. The IFTTT App can be very useful for automated systems.

From experience the heater control I'm using has a stellar record of dependability. I don't want to depend on cheap Chinese electronics to protect my battery investment.

My batteries are in an Off-Grid location that is used very little in the winter. I'm not going to keep the place heated when the batteries are the only thing that require heat.

What country do you live in that has a code against running water to a garage? I have seen more garages with water run to them for Water Heaters and Washing Machines than I can remember. In your unusual situation I would recommend a small expansion tank on the cold side of the water heater.

I still like the zero voltage required controller for my battery heaters. The Honeywell T6031A1029 is very reliable , easy to install and uses no power to monitor or activate the heaters. Why add another energy eating control to you system when there is a battle proven control that has been...

I have a Solar/Wind/Diesel Generator system. It is currently running on Lead Acid L16 Batteries and everything plays well together. I am putting together LiFePo4 batteries and have been looking for a way of accommodating the PMA Wind Generator. Looking forward to the write up. I have some...

This might be the answer to my system. I am converting from Lead Acid to LiFePo4 and have a PMA wind generator designed for Lead Acid. This would take care of the problem I was facing when the LiFePO4 are completely charged and the wind kicks up and needs a place to absorb the winds power and...
