I'll be placing this in the garage where the ESS limit is 80kwh. Are you suggesting connecting like shown in this post: https://diysolarforum.com/threads/paralleling-the-eg4-powerpro-wall-battery.67796/ That would be ideal and once EG4 gets those configurations approved that's what I'll be doing.

I'm trying to figure out the best way to connect 4 EG4 Powerpro batteries to 1 EG4 18kpv in a way that will pass inspection. I've mocked up some diagrams but let me know if I'm way off base here or if there is a simpler way to do this. I didn't consider adding all 4 to the same busbar since that...

The company I'm going with is charging $2.20 / watt and is using bifacial panels. Keeping in mind that I already have the inverter, batteries, and all cabling for that setup I had one company quote me $3.77 / watt for a 4.8kw system with cheap standard panels. The guy couldn't understand how...

That's still true. A plethora of Retail Electric Providers competing drives down the prices and almost makes it not worth the effort to go solar. And power delivery is very reliable as well. When I first moved to TX two years ago we had outages every time it would rain hard for a few minutes...

Found a solar installer and will be installing a 5.28kw ground mount alongside the EG4 gear. Payback, assuming all goes right, should be around 4.2 years. I've found that after reaching out to 14 companies, 3 will respond, 2 will be willing to do the job, and 1 will follow through. I shouldn't...

Does this 9540A doc indicate it is up to code to put up to six of these together regardless of number of inverters: link

My plumbing is for a swimming pool. I don't have any solar water heater panels.

https://eg4electronics.com/warranty <-- No mention of 80% DoD. Calee from Signature Solar also confirmed that going beyond 80% does not void the warranty. From what I've learned LiPO is less susceptible to the micro-cracking of extreme charge/discharge than other lithium technologies. But I'm...

That's the plan. Pay it forward

Don't know about other parts of the country but the pool should be running/filtering year round so it doesn't turn into a pond during the off season. Running when the weather is below freezing is to protect the above ground plumbing from bursting. There's the option of draining the above ground...

It's something I'm considering and, even with a 12 panel 4.8kw system at $240/panel (installer markup), it would lessen the payback period. The hurdle is talking my wife into it and then finding an installer willing to use my inverter and batteries. Not out of the realm of possibility.

Not a bad idea. I had no ideas timers existed for water heaters. Any time the temp dips below 36 my pool kicks into freeze protection mode which means I have 3.75hp worth of motors running. When we have the freezes it runs 24/7. Other than that heat pumps aren't as effective when it gets really...

My house is 3300 sqft and besides your normal household things I have: - 2x chest freezers - 2x Heat pumps (4 ton downstairs and 2.5 ton upstairs) - 2x water heaters that, combined, draw 10kw (These are connected in parallel. I need to change to series and use one as an in-line spare) - Pool...

Wow, in my evolving calculations I forgot to include a full battery recharge and was only accounting for recharging based on usage. This is why we do code reviews in software engineering. Changes the payback to under 5 years and the daily charge to $3.75. The negative numbers don't include the...

I'm assuming a total cost just under $14k. Always gotta ask for that veteran discount 😜 Currently I'm paying over $12/day but with net metering and monthly credit rollover I should be down to about $1.62/day. <-Assuming all goes right. This would lead to a <4 year payback.

My highest all time peaks are in winter at 29kwh during the freezes. Hence why I chose a hybrid inverter with 200 amp passthrough. My average peak usage for a month is 8.17kwh in July around 4pm. Average usage per month is 93.5kwh/day and $370/mo @ $0.13/kwh. My house runs on electric except...

Good question. I've taken my past two years of smart meter readings and loaded them into a database. Then I use excel and some simple sql queries to get my avg usage/month/hour so I have a starting point of my energy needs throughout the day. Once I have that I can start running scenarios for...

Rhythm: PowerShift Solar Buyback 12 And I was wrong about the morning peak; it's 6-9am. Evening peak starts at 4pm and Ultra peak starts at 7pm. The rest of the time it's ~$0.08/kwh.

Time of use as a backup plan but ideally planning to sell back to the utility during peak times 7-9am and 7-10pm. The rest of time use grid power at the off peak rate. This would make my power bills virtually 0. Keeping costs low this would lead to a <4 year payback. If I have to do time of use...

I am planning to sell to the utility / be connected in parallel to the grid. I'd rather not give insurance companies any reason to deny a claim if something goes wrong.

Looked up the state code 1305.00.6: work not specifically regulated by a municipal ordinance that is performed in or on a dwelling by a person who owns and resides in the dwelling; My local municipality requires a permit for everything over 24 volts.

This guy LOL. Sir you are sending me on a dangerous path that I am stupid enough to go down. But seriously, if that's the case then this problem just got a whole lot easier to solve. Thanks.

Never thought about those last options. I'll have to look into those. I have no idea. I would assume so. The last thing I want to do is void my home insurance because I have an unauthorized battery install. Permits for my city aren't very helpful here. There is a PV permit which requires...

From searching around and y'alls responses it appears that if you live within city limits and they require permits it's just too much of a hassle to do anything but hire a company to install and use their equipment. I have no idea why but just guessing it must not be enough of a profit margin...

Update: found someone to do the job. Thanks for everyone's input. Trying to keep my costs down so planning to procure the equipment myself and have someone install it. Looking for an electrician near Willow Park, TX who can pull the permits and do the things that only a licensed professional...
