Yes agreed, I have the JK bluetooth app on my phone. What I meant was, the app I had from Daly, I can access the BMS from where ever I am. For example, if I'm traveling, I can easily pickup my phone and see what the BMS was doing as the BMS itself has a wifi dongle that allowed me to connect to...

I would love to see what the 18KPV screen looks like when paired with the EG4 power pro batteries, in terms of what information is being displayed on the 18K PV screen, the mobile app and the web portal. This would be a really cool comparison to see how a DIY battery compares to the power pro...

Thanks for the feedback. For the Daly solution, there's actually an app that you have on your phone that allows you to control the BMS. Looking for something like this but your solution can work as well.

Thanks

Hi all. It’s been several months since I posted my review of the 18KPV inverter entitled “My Experience with the 18K PV Part 1 https://diysolarforum.com/threads/my-18k-pv-experience-part-1.70933/ Sine that original post, the 18KPV continues to work with zero problems. As stated in my previous...

yes, at the time northern only had inverter generators with less than 5% THD. Perhaps they've added some more models.

I received my numbers from the actual generator manufacturers. Before I got into solar, I was using a generator for house backup and did tons of research and reached out to several of the generator companies (before I bought the gennie) and most of them provided their THD numbers. The companies...

From what I can tell, the EG4 chargeverter is specifically designed to handle dirty power, clean it up and then send it to your batteries. When they speak of dirty power, they are referring to the quality of the sinewave produced by the generator which is also referred to as total harmonic...

For me it didn't make sense. I use alot of power at my home and running the numbers it wouldn't benefit me to sell to the grid at a much lower rate than what I would need to buy it back at. I also took into consideration my short to medium term power needs and it became really clear really fast...

Nice. Ideally just make sure the 2 strings that you are plugging into MPPT1, all of the panels in those 2 strings are facing the same direction.

Open vs closed loop refers to if the battery/BMS can communicate with the inverter. Open loop systems mean no communication. The inverter therefore makes its decisions such as low or high voltage disconnects based on voltage. Closed loop on the other hand means that the battery communicates with...

I was asked about how my 18K PV was setup in terms of specific config settings and thought that I would share those settings here (pdf file attached) in case a few persons find it useful. Just a few things to note. I'm using the inverter as if it was off-grid even though the grid is connected to...

Yes, it's coming. Taking longer than I had hoped given the issues experienced with the new JK BMS. Part 2 addresses DIY batteries with communication with the 18K PV.

Does anyone know if there's a way to manage/control the new inverter JK BMS remotely via the internet? I know Solar Assistant works with the older JKs although it doesn't seem to show individual cell voltages (not a big deal) and I am not sure if SA supports the new JKs as yet. Sent them an...

Hi all, just noticed today that the remote monitoring tool (web tool) for the 18K PV is now refreshing its data once per minute instead of once every 5 minutes. A very welcomed enhancement. Great job EG4.

Hi, can you send the link to the JBD that you are using?

Thanks, sounds like a decent workaround. Will probably make the charging window earlier to ensure I can start the charging during the higher SOC range but this could definitely work.

Hello and happy new year to everyone. I recently wired in my EV to charge from solar and batteries using the 18KPV and it has been working great. The EV charger is wired on the load output side of the 18KPV inverter and whereas this does work well, wiring using this method, the EV could...

15KWh for $3K for a completed server rack battery....compared to other rack batteries that pricing looks good but I can't comment on their quality as I don't know much about them. Their raw cell pricing looks quite expensive but the server rack batteries look like a very good price. I guess they...

Steve, thank you. I didn't consider the Chinese holidays. Will look into that now.

E EEL's prices on raw cells seems quite expensive...I think perhaps the most expensive that I've seen in a while.

Ok thanks for the comment. Who in the US is selling decent grade Bs right now with the fair prices? I got some Bs from 18650 which were great but they seem to be no longer doing grade Bs anymore. And Docan USA seems to only have the Eve 280Ks which I am staying away from for the time being.

Hi all, has anyone had any recent experience shipping cells directly from China to the US that you can share how long it took from the time you placed the order through say Alibaba to the time the cells arrived at your door? Thanks in advance.

@1201 No, not full retail. I saved a few bucks on what I guess were some of the early units.

Hey Adam...tell me about it. It took much longer than I thought it would've. My original plan was to use 8 panels per MPPT when I was going with the 6500EX inverters. By deciding to go with the 18K PV instead, to take advantage of its larger MPPTs, I needed to do 10 panels per MPPT. Those 2...

Before I get into my experience of the 18K PV inverter, I owe this community a debt of gratitude. I started this DIY solar journey back in Jan of 2022. At the time, I didn’t even know what an ampere hour, KWh or BMS was. It was because of this community and some persons on YT like Will, Andy...

Nicely done Markus.

Looking forward to seeing further updates on your project. I'm international as well. Tell me, are you using 50Hz or 60Hz in your country? I'm 50Hz and the 18K PV inverter is supposed to accommodate for that. I'm hoping to have my 18K PV setup and connected to the house soon. Just finished...

I'm in Barbados.

Received the 18K PV unit. Will be starting the setup process this weekend. Looks very well built. I had to do some minor work at the house to get the panel configuration that I wanted and that was just finished 2 days ago so I have a 5KW 10S string to work with so glad that was done in time to...

Lol...

I'm feeling like an 8 year old on Christmas Eve. Got a notification that my 18K PV inverter has arrived in my country, cleared our local customs and will be delivered to me tomorrow. I'm planning on doing some reviews of this unit. Really excited about getting my hand on this.

Nice. Thanks for the reply. That's really encouraging to hear.

I'm looking at a similar setup. How has it been working for you? Any stability issues? Is this CAN or RS485 communication?
