    Sungold wiring help please

    Fault code 59 is a "Minor BMS Fault". If you run the IPower.exe (or iPower-nt.exe) that SunGoldPower can provide you (or you can find it elsewhere) it will display 59 as "Minor BMS Fault" at the bottom of the screen

    Cannot get BMS Test working on EG4 LL battery

    Did you download https://eg4electronics.com/categories/batteries/eg4-ll-s-48v-100ah-lithium-iron-phosphate-battery The readme.txt file says: This firmware can only be used on the EG4 LL-S (EG4 LL V4) battery. The purpose of this firmware is for the RSD function in closed loop Communication...

    Anyone else with a recent EG4 48v Lifepower4 battery purchase getting a "Charging MOS fault alarm" that can't be reset?

    If you are not running Version 3.37 firmware (have an older one) and you are using an EG4 Communications Hub you will need to update to v3.37 as the firmware update increased the baud rate on the pins 7&8 RS485 port to 19,200 which is what the BAT Input on the Hub requires. This increased baud...

    Cannot get BMS Test working on EG4 LL battery

    The BMS_Test software communicates using a HexAscii format using the EG4/Narada protocol whereas the BMS_Tool uses a Modbus format. I suspect the EG4-LL series batteries to not speak the EG4/Narada protocol The EG4-LL-SS and EG4-LL-V2 firmware downloads from the EG4 website also include the...

    Is the Eg4 Lifepower4 battery worth the low price

    The auto update tool is locked into the firmware version installed when shipped and as the auto update tool installed firmware cannot be updated. I believe the latest firmware is V3.37 The BMS_Test tool can upgrade (and downgrade) the firmware (so far). It is also nice to have as it lets you see...

    The CAN/RS485 ports are used for BMS to Inverter Communications The RS485/RS485 ports are used for battery to battery communications The RS232 port is used by SA or PC based monitoring software. For the SunGoldPower batteries you would want to connect SA to the RS232 port on the master...

    Battery shutting of at 40%

    You need to find out if the manufacturer has the correct cable to connect the battery to a computer. If not it may be possible to build a cable but you will need the pinout of the RJ 45. The battery RJ 45 more than likely uses either the RS485 or CAN protocol (or both). You will need an RS485...

    Battery shutting of at 40%

    If you purchased the batteries with a communications port you can download the software from https://sakopower.com/download With this software you can monitor the batteries. To get the battery BMS to balance cells you will need to charge with 56 volts (16 cells x 3.5 volts per cell). Most BMS...

    Massive SOC variation on EG4 LifePower 48v

    If you provide a charge voltage of 56 to 56.5 volts while monitoring the batteries with the BMS_Test software you will start to see the BMS for each battery begin to balance cells when the cell reaches 3.45 volts. This will be be indicated with a 'Bal' next to each cell. Once the BMS starts to...

    RS485 connection between LVTOPSUN and JK BMS produces Magic Smoke

    Do you have the pinout for the RJ45 jack on the battery? You will most likely need to make a custom cable that only connects RS485A between the inverter and battery and RS485B between the inverter an battery. You may have inadvertently connected ground (or power) to an active pin. As stated...

    Voltage on UART pins

    The minimum and maximum voltages of a true RS232 signals are +/- 12/13V., while TTL signals are 0 to 3,3V/5V. The differences between a TTL RS232 (also called RS232-C) and a True RS232 interface is only related to the signal level to GND (Ground) and not with the current to power the device...

    JK BMS - Does It Recalculate Capacity?

    I have found that charging a battery to where the BMS starts balancing the cells (and holding this charge voltage) but no cell reaches OVP will reset SOC to 100% and this 100% appears to be accurate with respect to battery capacity. Driving the charge to a single cell OVP will not necessarily...

    Negative terminal bus bar help

    The batteries would normally be connected to the bus bar using the smaller M8 bolts. The inverter is then connected using the larger M10 bolts. Generally you would connect the inverter to the top most M10 bolt on one bus bar and to the bottom most M10 bolt on the opposite bus bar. If you are not...

    Eg4 life power4 battery won’t wake up

    You need to use the EG4 provided software and the correct communications cable to "talk" to the battery. The BMS holds a lot of information including what is causing the "Alarm" light to be on.

    Solved! EG4 Lifepower4, 6000xp, and solar assistant

    It would help if you let us know the batteries you have (i.e. EG4 LL, EG4 LL-XX or EG4 LifePower4) The EG4 batteries will communicate with the EG4 hub on pins 7&8. The batteries need to have addresses from 1 to XXX and the hub is address 0. SA will happily communicate with the batteries on an...

    Extra/Auxilary grounding rods..... Don't do it.

    Lightning happens when a really huge negative charge builds up in the ground, corresponding to a positive charge overhead, and the differential becomes sufficient to jump the gap. (and, as others are pointing out repeatedly, air is an excellent insulator, so it takes a whacking huge voltage...
