is it haunted?

hey can you pm me the sales.contact or link？

we don't have that much space on the lot; entire lot is like 250 sq. meters, much of that is occupied by the house. Probably will build a carport using bifacials though.

true, no gps constellations yet :)

The roof of the house we bought is totally shot, it all must be totally rebuilt (rafters and all). So I'm thinking to just make a flat roof tilted at a certain angle or angles to optimize our solar production. We'll make it generally South facing and the builder said he can do about a 20 deg...

Ah I only needed one (3.3kw array). I went a bit crazy with the PowMR because we were able to get them so cheaply. I was thinking to redo my setup so 4 panels per charge controller. I was able to get a "used" epever which was just a return for $160 including the MTS50. I did not buy three of...

So in the past I've had a couple of their older mppt models (metal housing) they worked ok when they worked. Very touchy if you accidentally loose battery power while connection with panels plugged in they would die. I recently bought 3 x new powmr pro 60 amp 12/24/36/48 mppt chargers...

Just wonDering if you have an update. Is the Sunkko balancer still working well?

Exactly what I need. Thank you!

Thanks Don but i know how to just do a step down. For that I'd prefer a buck converter as it's less wasteful

I have a few related issues ... 1-I would like to make a DC USB PD charger for a laptop which needs 100w. House voltage is 48v. Most of our things run on DC, fans, lights, USB charging etc. Is there any special circuitry required or is this as simple as sending 5v over a 20v USB line? I...

There are convenience shipping places like Mail boxes eetc everywhere in california, the state is literally the 6th largest economy in the world lots of shipping conveniences. If this guy is real i sure hope he will at least upgrade your shipping at this point; it's the human thing to do

yes Frank, something smells funny to this situation. so it starts as "pal has back surgery" then the guy falls off the face of the planet and is irritated you are concerned to get your stuff? He knows your family is totally off grid so without the stuff you are down in battery power ... so...

Hehe for sure nobody is worked up for 9 months already :)

Yeah I know but these will be at different locations. a PI is really overkill for what I want to do (though cool for the project being discussed in this thread) :) I only need to do occasional reads and command issuance and ESP32's are like $3 here.

So did we decide it shows power in + power out from battery? lol

Have you ever figured out what the Amps on the top right of the screen is telling us? Is it the amps in + the amps going out? Is it the amps in offset by amps going out? etc. Yesterday around 5pm (dark here at 6:30ish usually) mine was showing 55 amps (on a 48v system). I only have a 3kw array...

yeah that's the site.

Thanks, I'll probably use my old Pi to get things rolling then *if* I get it all working I'll play with the esp32. I'm not so much interested in cataloging the data as much as being able to send and receive commands to the BMS in an automated fashion and I dont want to buy a bunch of Pis for...

Me too. I've had 2 of these burn up. 1 charging mosfet just failed (the BMS had gone into short circuit protection and never worked again). 2nd one claims wires disconnected; I checked the soldering and all is good so who knows. After that all is golden though so I have parts from the first 2...

BTW not sure if you've seen this, these are pretty close to the values I use. Will has a sticky note, I use the values for 5000 cycles. I set it slightly different to account for voltage drop. BTW where are you located (country)? I'm in the Philippines (expat)

Did it seem to work setting things in the pC? one value you may want to change, I made the "Max amps utility can charge battery" very low because I don't really want the utility charging it at all unless it must at night due to my DC draw. Otherwise you end up with excess (read "wasted") power...

haha sorry I'm only on every once in a while. So, I would not do the settings over the computer unless you find them working. The menu is confusing as I recall pressing menu did not bring up the actual menu, instead you have to hold down <enter> for a few seconds then [01] comes up. Press...

Has anyone tried to connect to an ANT BMS using an ESP32?

@fhorst do you still have the link to the factory you sent me last summer? I can't find it. I was in communication with someone at the factory for a while (2 ANT BMS mysteriously died)

Oh you mentioned brownouts... we usually don't notice there is a brownout until a text comes in from the power company that power will be restored at such and such a time or we are on the terrace and notice the neighbors' lights are out. Really the inverter should just not feed the grid when...

My pleasure. So here's a suggestion, there is a "program" in the menu where you can set the MAX amps the grid will charge the battery. I have mine set to be just a bit higher than my max DC usage at night b/c I don't want to charge up the battery fully in the night (paying for it) when the...

OK so here is where you can get pdf versions of the manual (for my model the printed manual is most up to date). With my model I can change all of the charging profile options. You just have to hold down the <enter> button for a few seconds then the 1st "program" item appears. You press...

another thing I noticed, the manual that came with mine is more up to date than the pdf they have online ... dunno if it's the same with you but dont loose that thing. read it through several times... feel free to ask more questions

I have a Must Power hybrid also, and it sure seemed to me like it was feeding the grid as well. So what I do now is I have the AC line in connected as a plug so I unplug the grid until the inverter beeps haha. On sunny days I dont need the grid for full 24hour cycle so no beeping. If it beeps...

Haha thanks, you and I both missed that earlier today when I sent it to you fhorst in chat before posting with the same chart! what are the odds! :LOL: BTW I also have some "EVE 120 AH" and 1 of them very strangely totally behaves like it is shorted internally (shows 0v and will accept charge...

Hey all, I ordered several EVE 280's from a seller and the first cell I capacity tested stopped right at 272. Here is the code on the cell, the "vendor code" is not 04Q EvePower" but instead is "02Y" and the Specification code is different as well. I'd be very interested to hear your comments...

THis is something important to know. I had watched many videos, read lots, had inverters in the past etc. but when I got my 6kw inverter I had never read thatyou could expect for the inverter to ALWAYS consume 2-5% of it's MAX rating even when it's not working so hard. I would have gotten an...

I think the PC option will work. In my case, I connect via PC to the 485 port. The Uart to USB did not work for me. I've had no problem setting all the values on both defective Daly 250a smart BMS I bought using the 485 to USB cable. I wasn't able to set values in the bluetooth app either so...

The Daly BMS bluetooth only works with very new devices in my experience. The newer higher amperage BMS they sell seem to be VERY erratic and unpredictable. I bought a 250a 16s it worked for a few days then just turned off never to be restarted again after trying all the suggestions on here...
