The battery should have BREAKER for over current protection, it will be enough to protect your system. but, MUST BE A BI-DIRECTIONAL DC Break, some battery supplier use AC breaker, and it will have huge delay to trip under over-current fault. and then, need a FUSE. Note, The most DC breaker is...

For long term use, 3.40V per cell is the enough voltage to charge LFP battery to full, the charging late is 1/10C rate. 3.45V per cell is the enough voltage to charge LFP battery to full, the charging late is 1/5C rate. 3.50V per cell is the enough voltage to charge LFP battery...

I have similiar experienced while upgrading firmware, it has stuck at 9x%, and reset by itself, and stacked in black status. but, my device had connected with gateway (insight home/facility), and xw pro is showing nothing (no led/display) like as turn-off, When I have power cycling (turn off...

Power Cycling Again, and then, update firmware again. your XP Pro should be in Bootloader mode for firmware upgrade

i am using XW pro with 30kWh for temporary backup, and using a fuel generator for long term back-up. I have 8kW, and average power usage is 16kWh/day, worst solar energy (cloudy & rainy days) is 6 days in my place, and storage demand is 106kWh (it means, I need 106kWh*110% to be independent from...

Maybe a portable generator should be better, and 33kWh is too small I guess

many houses are sharing a transformer, and, everyone may have a different system.

1. Schneider XW Pro 6848 2. 48V (51.2V) 3. 6.8kW 4. 6W in Standby mode, 16~18W in operation (idle mode) are measured {From Battery] Note : SCP use 0.2~1W, Gateway use 2~4W have included in #4

Unfortunately, super capacitor in the active balancer has the limited cycle life. If operating the battery pack in top-up position (most full status), balancer will cycle the capacitor too many cycles, and practically, can standing 2~3 years for 1A, 3~5 years for 2A. the super capacitor is not...

I think, the current cost is around $110~130/kWh now, but, Cost will go down under $100/kWh soon, no need to hurry if not urgent. Factory cost is around $50~60/kWh in China.

if the noise is not coming from your next door, there is no other solution except trying to use the different firmware such as v1.11_BN0028 or 49.

If the noise is happening in Standby Mode, need to contact on Schneider. I have got the similar issue with you, Hum while always http://www.bomijoa.com/files/se/se/IMG_1092.MOV No hum while inverting (AC IN ON/OFF Both), just Humming while AC Pass Thru...

While PLS is working, charger function will be disabled. http://www.bomijoa.com/solar/?detail=0&offset=0&size=1&debug=1 on 4/28 at the first graph 00:00 ~ 06:00 - PLS, so, no load from grid 06:00 ~ 13:00 - Main solar generate power and export to grid, and using small amount. net...

while adjust the setting, firmware can be messed especially, Grid Reference Voltage Selection as Dynamic, Association, and Factory Reset. I have tried to adjust/charge in BN0049, but failed in my trial. so, I have restarted from the previous version, and makes it working let me share what I...

I understand as you want a back-up batteries to save an energy at day time, and use it at night. Unfortunately, there is no cheap solution. Anyway, You are using Enphase system already, it is AC system. so, you need an AC Coupling solution. Basically, AC Coupling means, (1) switching box...

I feel, your problem is not an issue from the firmware bug, Two inverters have not reporting day from 27 Apr 08:06pm/10:56pm (I feel, some timezone issue) The data has captured on28 Apr 2020 12:24pm * you may need to fix to show the right local timestamp. Anyway, the 5 min production drop...

You are lucky if you have got a good inverters, anyway, firmware version of your device & my device are same, I think the lot in 2019 version has an issue, my devices serial number is starting as 121944xxxxxx. I guess, 2019 versions. One of replace version is 202040xxxxxx, not sure why this...

Not in enphase.app, if use PC, can see more detaenil device information at ( enlighten.enphaseenergy.com ) or can get the information from Envoy. My firmware version is v04.28. the first page - Status - Dvices on Right side - Micro-inverters there is a Firmware version numbers I have hared...

The problem is not special in Enphase IQ7+ also. You are lucky because you have fixed with FW update. BUT, my case, never fixed. still have an issue. IF do not mind, can I know your firmware information ? version and build date...

Hi, How are you? Can I get an advice for my issues ? Gateway has updated to the latest version (1.16 b4) I have been using FW 1.11.01bn28. but, it lead some voltage drop while export power (for sell or PLS). even lost AC qualification when exit from PLS mode by stop time setting. I have...

Multiple battery voltage chart needed via temperature, charge and/or discharge current. while charging the full charge voltage is over 3.45V, but, while discharge full charge voltage is around 3.35V. every battery manufacturer has the different voltage profile. And, need to track the lowest...
