Would be glad to find one. Do you have a source? I did some quick searching and found nothing comparable to yours.

If the comms are absolutely necessary to you, and you have not had the batteries long, I would try for a return and find another battery that will fill your needs. There are other batteries that offer comms with Growatt inverters. You can also give your credit card company a try in recovering...

I just bought the same model in January and the power save function does work to save power. I have one issue with it, when a load is applied, it doesn't wake up.

I have done a reset several times. I have also set the setting to call up "Last" and to "Default" settings. This recalls the last used settings, or the default settings. Neither work. If I turn off the unit, unplug it and then turn it on again, it goes back to Chinese. I have tried everything I...

I have built another ground mount earlier this year, see this posting: https://diysolarforum.com/threads/from-growatt-to-victron-energy.30978/page-2#post-384115 This ground mount is much bigger now with twelve 320w panels, built with steel channel strut, and is secured with 36 inch rebar...

Nope.

I sent the oder ID per email to sales@jakiperbattery.com. I also wrote that the batteries are connected in parallel with two Signature Solar 48V/100Ah batteries, and they do not play well together. The Jakiper batteries discharge faster and charge longer than the Signature Solar batteries. I...

I have four Ampere Time 200Ah Plus batteries. Two I have tested completely, and two are testing now. The standing voltage of mine are between 13.7V and 13.8V after about one hour. So I would think that 13.6V is OK. The CHINS batteries I had did not cut off even at just above 8V. I think that...

I posted here, and I emailed them. Saw your reply for Ohio delivery and gave it another try. It worked. I have to pick them up in Ohio at a freight hub. I am happy. This has been a long wait.

May I ask what your charge time is the your set up? I know that is near impossible to answer, but say you have 50% SOC, what is the approximate cahrge time with you panels. I have 10 HQST 100W panels and I would over panel a little (keeping voltage below 145V), and would like to know what kind...

Having to deal with the sudden surprise of permitting/zoning of my solar system. Project shut down until inspection and passing code by certified electrician. Also need approved zoning for my panels. I am doing a ground mount in my yard, and that sparked all of this. Living the dream. Welcome to...

Got an updated delivery date. Mine are delayed and will now arrive on January 11. I hope this is not the beginning of a pattern.

I looked at #24, and it is only available when connecting Growatt's in parallel (expansion). I am not sure that any parameters above #22 can be accessed. Thanks!

I thought I would close this out. My inspection was completed and we passed, I am still awaiting the zoning to pass for the panel installation. I ditched my Growatt inverter due to issues. See the following thread...

One more thing, please make sure that your firmware is the latest version. The newest firmware adds more functionality. Glad to be of help. This is what I think this forum is for.

I have three Solarever 440W (SE-166*83-440M-144) panels for my secondary small off grid system. The panels are over a year old and they perform flawlessly. The three panels produce about 1230W in full sun. The panels work great on cloudy days as well. The build quality is great, they perform...

I wrote to the shipping company (ABF Freight), they informed me that there is a major backlog and a shortage of drivers. My batteries are sitting in ABF Freight's center in San Bernadino, CA awaiting a truck for loading. They cannot give me a delivery date. The delivery date will change on their...

I don't know what you mean by Tier 1? I know what Tier 1 solar panels are, but that will not help me. Can you elaborate please?

Nice job, hope it works out for you. May I ask if your Easy Solar is a 230V or 120V system?

These units are no longer available.

Could you send the specs on your panels. You should have a sticker on the back with the following and more: What Brand and model so we can identify your panels. This is very important. VOC= Voltage Open Circuit IMPP= Max Power Current Max System Voltage in DC If you can, take a picture of the...

The company I worked for used TEG Generators on the natural gas well pads. I called one of the techs and he said that most TEG equipment is industrial, however he gave me a few web sites to pass along. https://tecteg.com https://thermoelectric-generator.com/ https://www.tegmart.com/ He yold...

I just talked to the dealer, and he wants to send me a replacement unit to see if that solves the problem. I have my Giandel 2200W hard wired into my system right now, and I will leave it until the replacement unit arrives. The dealer and I are both worried that this problem may be a feature and...

Look at this thread. https://diysolarforum.com/threads/ampere-time-200ah-lithium-any-reviews.11161/ The Lion Energy batteries are great. I have 4 in parallel that I built into a mobile unit. See pics. They are stable, perform far over their rated capacities and all aspects of the BMS work as...

I think I have found a very good use for my excess power. All of your ideas have lead me to research a water heater we used when I lived in Germany. Mini Tank water heaters that use 120V from an outlet. These are actually very energy efficient and provide enough hot water for most uses, and I...

I realize this post is months old, however, I bought three of the 440W modules with the intention of connecting them in series for a 150V, 1.3KW system. I will say that the panels do pack a punch and really crank out the power, but there is one inherent problem with them. They are rated at...

I have actuially had to unwatch my own posting. How pathetic.

The cables are 4AWG. 2AWG is recommended by Growatt. There is a 2/0AWG connecting the two batteries in series. I only have 2/0 cable on hand for my batteries, and will probably have to get 2AWG because the 2/0 cable doesn't fit through the cable opening. I really really tried. I don't even think...

As per your instructions, I removed the display daughterboard from the old BMS and installed it on the new BMS you sent me. After swapping out parts from both BMS's, I installed it, now the BMS functions fully and the battery is now working as it should. Thank you.

Thanks Snoobler! Big Time. I had a 24V Growatt that ended up having to be returned due to wild voltage fluctuations. Since then I have been running a Giandel 12V 2200W inverter with no issues, other than I need more capacity. So my batteries are already in parallel and fully charged. I like the...

I received and email from a freight company (Freightera) that my Jakiper batteries are on their way. Expected delivery date is January 5th. I would expect that others will start getting their notifications real soon if they haven't already been notified.

In case anyone is interested, the issue with my Jakiper batteries has gone a little south, ABF cannot find them. I started a new thread to let people know what is going on. Will has actually jumped in to help, and I am grateful. See below...

$75.......Great deal! That really payed off.

Thanks!

I have been super patiently waiting to see what issues Bluetti 200 series units were going to have. They suddenly started adding the additional warranty on those units seemed strange to me. I am now thinking that Bluetti is not the way to go. Does anyone have any experience with the Inergy...

If you are interested, I had great luck with the brand Vottery on Alibaba. The batteries are also 105Ah like the Lion Energy batteries, and perform the same. I have two of them connected in parallel. The only thing is they do not have low temp charge disconnect. These batteries are also in a...

If I were you, I would put it to them to find out what they can do to ensure that this communicates with your inverter as advertised.

I talked to Ian just now. He told me that the AC charger is also highly configurable, and the output can be dialed in to whatever is needed. My LiFePO4 batteries recommended charging is 40A. That can be configured. I am liking this Growatt and can't wait till it gets here. Thanks for the...

Just a heads up. the mystery of getting 48V MEGA fuses for the Victron Energy Lynx system is strictly limited to the 125A and up. If you need anything lower, you are out of luck. The ONLY manufacturer I could find that make compatible fuses is Littlefuse. They are only available in the 70-SF51...

I just wanted to post an update. There is none. I am still waiting for my zoning permit, and the electrical inspector has not even contacted me to set up an appointment yet. I was told that the inspector needs to get up to speed on code for solar installations before visiting me. We made a lot...

I wish I could say that the ground was my issue. We went over every inch of the installation and could not find anything. I had two certified electricians helping me and it was determined that two inductive motors (fridges) running at the same caused the extreme distortion in the voltage and...

The Quattro can do off grid only as well. But it sound like you want to step down 240V to 120V.

Thanks! Big help. I will post the results.

Have you tried https://community.victronenergy.com/index.html

How some people can make you regret trying to help someone out. I regret poting this and have had enough of this forum. It seems that no matter what you post, there are always those who have the crappiest attitude on someone trying to contribute and help out its members. No manners at all. This...

I just ordered the PowerMax PM3-45. I will use it exclusively with the Lion Energy batteries. Thanks for the tip.

Merry Festival :) HAHA! Read the whole posting closer. They need to hire a good english translator.

I looked at your diagram. So you are saying that the ground provided by my house's panel that supplies AC to the Growatt should the source of my ground? I currently have my Growatt sub box providing ground to two 8ft rods we put in just for the Growatt. Your diagram tells me that the isolated...

I got the battery out of my server rack, opened the top and removed the server rack mounts to expose the screws for the faceplate. Nine screws and the entire from comes off. Getting the BMS out was a breeze thanks to HighTechLabs's tip. Thank you! Now for the most unbelievable news. I opened...

The battery has M8 screw terminals. Use a 5/16 lug.
