    Sunny Island parameter? GDAISns

    Does anyone know what theparamter GDAISNS does? settings are high normal medium and low. The context of my question is: we are grid tied and if the power blips for a few ms, it's enough to make the SI drop the grid. It should reconnect in 5 minutes but it sometimes does not. Actually it's...

    SolarEdge 11.4kw

    I have an older SolarEdge 11.4kw inverter that does NOT do frequency shift power control. I’d like to upgrade to an inverter that does do frequency shift power control so I can put it behind my sunny islands. HD wave comes to mind…. Are there any other models I should consider? Was there ever...

    Sol ark runs generator too long?

    I have a friend with a sol-ark and 10kwh of batteries. He's not making it thru the night and the solark starts his generator just as it should. But what it does is charge his batteries nearly 100% before killing the generator. This mean the batteries are full when the sun comes up which is...

    We've got a precedent club cart golf cart that I converted to LIFEPO4.

    When moving slowly or under a load the throttle just dies. I thought it was a bad position sensor on the pedal but I'm starting to think otherwise. If I just stab the pedal and go, the cart seems to work better. In my case the cart dies and coasts to a stop. If I release the pedal and press...

    Forcing Sunny Island SOC

    I'm running a home brew pair of LFP batteries with two BMSs. I've programmed the Sunny island 6048's to shut off at 42v. I'm not using the current shunt because I have two inverters, two batteries and a pair of morning star charge controllers. I would have to add another busbar into my system...

    Overkill / QUCC / Overkill BMS timeout

    I left my pack on but not connected to any load for two days and when I came back to check, it had shut off the contactor. A quick connection to a 10ohm resistor on the battery leads woke it up and caused it to pull in the contactor. I’ve been accessing it via the XiaoxiangBMS app on both ios...

    QUCC BMS

    I’m pretty sure the 200amp QUCC bms is a knock off of another brand. Is there any iOS app for this BMS? It came with a link for android but I don’t have an android device. It also comes with a link for PC software. I haven’t tried yet, but I wonder if I can connect to it with a bluetooth...

    Sunny Island easy shutdown?

    I read the manual today and saw that the DIGIN pin cannot be reassigned to another function on my 6048 Sunny Island. DIGIN is used to signal that the transfer switch is in GEN or GRID position. The two relay outputs can be made to do all sorts of things. Does anyone have any ideas for a way...

    Turn Daly BMS on the easy way

    I have read the threads here about how to turn on the Daly 16s 250amp by connecting P- to B- while a charger is connected. It all seems rather hokey. So if you didn't know you needed to get the LIGHT BOARD/ POWER SWITCH, here's how to do it... You need an 8 pin JST PH 2mm spacing female plug...

    Sunny Island / Chargery issue?

    I’m using chargery coupled to their DCC, and noticed something the other day... when charging the battery from a morning star charge controller, I noted that the charge side of the DCC was shutting off. Battery voltage was about 3.23v per cell and no cell was anywhere near 3.6 yet the BMS was...

    Latching Chargery DCC off

    Given that the chargery DCC does not do soft start when commanded off and back on, I'm seeking ideas to make sure it stays off if it is shut down for low voltage on the discharge mode. I've got a HUGE battery and if it goes dead, I got bigger problems.... I don't mind if the inverters stay...

    Battery Setttings for Sunny Island with LFP

    I searched the forum and didn't find the answer so I'm asking. Hope I didn't miss the thread I'm looking for because I can't be the first to ask. :) . Does anyone have the battery settings for sunny islands running LFP batteries? Section 220 covers battery settings.... I expect to disable...

    Chargey DCC surge protection.

    I’ve read the manuals I can find on the chargery site and I’ve searched the forum here... I must be missing it.... can someone tell me the correct power up sequence? I imagine I turn on my intverters‘ breakers first, then power up the BMS which turns on the DCC... and I expect the DCC will...

    Chargery remote cable length?

    I'm new... can't find the answer on the threads.... I'm about to buy a chargery 16s unit and want to know the max length of the cable to the remote can be? My batteries are in the basement and I have an existing 40' cable from an older inverter remote already in the walls. Also, whats the...
