I like it, rather rotary switch and no hold current but tis is fare more economical 1-1618002-1 EV200ADANA High Voltage Relay Coil 48-72V For TE New Energy Vehicle https://www.ebay.com/itm/354844268449

Fuse inline with the Disconnect at the panel and a disconnect in the area of the MPPT. Fuse protects the wire from the power source and double disconnect insures I won't get 'blasted'. The MPPT from inverter from the EG4 puts out voltage without the solar. Have to protect you from both...

I have been looking for a automatic or remote battery switch that can handle 48v batteries. I would love to give BEP MARINE 720-MDO motorized switch. The motor runs on 12V but capable of switching 500A at 48V. This would make a great emergency shutdown to an existing system. For around...

Now that is a serous DC breaker assembly. I found a couple for sale on surplus. Can't wait to hook them up with some bullet breakers Electrical Nominal Voltage -/+24-48V DC Voltage Range -/+19-60V DC Number of Buses 2 Bus Rating 850 Amps Max. Interrupt Device 1000 Amps Number of...

I tried again on a different computer. Microsoft and Google both find it dangerous. Why the download was blocked Your file download may be blocked for one of a few reasons: Dangerous: Malware (malicious software) Deceptive software that could make unwanted changes to your device or computer.

I didn't install the software or should I say run it. I unzipped it and copied the older version into a different directory. I was going to use it after work that day. Then windows flagged it was a virus and quarantined it. I didn't have this issue on the older version that I ran a few...

I just downloaded the latest file from the EG4 website and did a full scan. This is what I found : Win32/Bladabindi!ml

I haven't measure specific gravity in years. I top them off with distilled every couple of months. I have pick up a kit. Having the solar panel there to protect the tires will probably cause more issue with drying the batteries :fp2 I had thought about putting a fan in the cabin to help keep...

making a small wall of panels like 4 305 watt that I have. I like the idea of the plastic water drum as a ballast. similar to this but with drum that can be filled up

The wife wants me to cover up the HVAC, Pool Pump, water softener, and all that 'ugly stuff' that can be seen by the pool and porch. The pool pipes go through this area so digging down and putting a fence around here is a little challenging. I came up with an idea. How about something I can...

I have had many boats and this one for over 24 years. I have had very expensive batteries and now run inexpensive Wally World batteries. Usually get 4 years out of them. Before ever weekend trip I'll bring out the extension cord and do a overnight charge. In my quest to make everything...

Nice work, I am not into 3D printing yet. Anything that I can purchase at a reasonable price and mount to a 19" rack? Would prefer something that didn't have open wires/connections to short out. Needs to run on 4 through 28vdc. I can upgrade Solar Assistant from by RP3 to Orange to make it...

I found this https://diysolarforum.com/threads/soft-start-on-2-stage-ac.42328/

Here is an example of it learning 1st time and after 5 times

I have wanted to buy a transformer that can take 120Vac and go to 230-240Vac. I see a bunch of inexpensive toroidal type on various platforms. Price is getting to the point that I want to try one. Anybody have any experience on them? Voltage Converter Transformer 5000-Watt Up/Down...

The soft start is powered by the contactor when the demand is there. I went from 109amps to 39 amps on a 5T unit. Lights no longer dim in the house. Very happy with it.

you have to look at your break even cost for the solar. I have battery backup and that justified the system expense to have have the system. Payback time is 8 years at current rate. Backup Power with solar charging benefits and piece of mind. A few more panels and price will keep going down.

Storage is one thing but charging is another. Manage your loads and HVAC by not trying to keep the entire house going as usual. Solar, Grid, or 500-1000 gallon propane tank with a generator is your temporary answer

I just saw this one, I told the wife "See it isn't my fault" Solar Joke:

I have a couple of ECO-WORTHY 12V 100ah and haven't had any issue with them. Sale on AMZ with free shipping was to much to pass up. Their rack and tilt mount is pretty inexpensive on fleabay. Never tried to call them. I have a car stereo and speakers set up on the porch and another on a 2k...

I have had it hooked up for a few weeks now and have no complaints about the VSD and the pump spinning up, slowing down, heat, alarms or any pump related issues. HOWEVER, my salt water chlorinator doesn't like it at all. I get low salt & low flow alarms. I can see if you used this pump...

Nice breakdown of what goes on inside a breaker:

My little 3K (going with 2) need 80A each so this may be my best fit: Midnite Solar, MNEPV80, Circuit Breaker, 80A 150VDC, 1-Pole, DIN Mount (BI qy29u280b1zl) Accepts up to #2 wire https://www.amazon.com/dp/B06Y1KNDCR https://www.stellavolta.com/MidNite-Solar-MNEPV80-Circuit-Breaker.htm

These instructions are for bending the input/out terminal https://www.altestore.com/static/datafiles/Others/MNEPV80-100_Instructions_V2.pdf

Let me know how that turns out. Now I want to build a load bank and torture test everything! The fact that it will do AC and DC is interesting. I still see +/- for the DC on the breaker.

The cable was 4-AWG thin strand tin plated. It was torqued down as much as you could without breaking the plastic. It was still tight when I removed it. The wire was oxidized and the insulation slightly melted near the breaker terminals. I cut the breaker open and besides for the heat at the...

Was thinking of something like this for the battery to inverter breaker: MNEPV 80A Din Rail Mount Breaker To 150VDC Some #4 & #2 Ferules too

Speaking of Circuit Breakers, I find myself looking for a good reliable one also. Installed for 11 months with no issues on a EG4 3000. Used supplied breaker and wire. Wife running a couple of things in the kitchen and it overloaded reset and kept working. Came home to find the breaker...

Just to throw another one in the ring. The beatings will continue until accuracy prevails! In fairness this was designed for a 48 volt system. Everything was divided down to the other voltages.

Thought exponent, don't try this at home until they do and tell you it worked... Can you have a small PV setup with microinverters connected to a EG4 3K output? Say you have a shed way in the back yard that is fed 120Vac from an Hybrid Inverter on the other side of the property. "What if" you...

Surge Protective Devices This globally-compliant, cost-effective Type 2 Surge Protective Device has higher nominal and total discharge current protection. This limits transient overvoltage to equipment mitigating costly damage & downtime...

This is what the wife uses. Usually a bunch of fungus indicates that the plants/soil are too wet. We use pretty warm water when mixing, shake well. If it sits give it a good shake again.

Living in Florida we find that lightning & hurricanes are more of a threat than CME & EMP. I install ferrite for RFI (Ham Radio), surge suppression, and an extensive ground/bonding on everything. I don't expect to escape damage from a direct strike but a strike near by is enough to cause...
