Hope @TaliaB to recover to good health soon .

I have some Epever XTRA 3415N 30A units that I have used with Pylontech batteries . They are 150v max units .Connected 2 of these to the battery busbar and 1 strind to a 145v Axpert. 4kW These units have their own program and can be setup to run with your current system . Can be programed to LFP or user settings Programming can be done using a PC .My Axpert had no communication with the pylontechs. This system was connected with Solar assistant so I could see some of the battery info . I have upgrade to 6 kW inverter and dont use them .

Weigh the battery u2000 50Ah is 24kg and the U3000 74Ah is 32kg .

Need help to connect Hina battery to Hinaess app. Battery is connected to Luxpower inverter and some battery info is displayed on Luxpower app .

No they are sold .

BMS settings 25.6 volt 2.71kWh SVolt I used the RS 232 port and made a cable to serial 9 pin connecter and use Pbms 2.4 PIN 3 TX PIN 4 RX PIN 5 Ground There is some info on this forum to use the CAN port to USB

Item : 2 Pylontech US 3000 SOLD Age 6 years Price R3000 each Payment EFT or CoD Warrenty None Package None Condition Normal . Cell info Multisub avialable. Parallel cables included. Location Heidelberg Gauteng Shipping Buyer Collection Yes Reason for selling . Upgrade system

S Volt also makes a 325 AH 51,2V battery on wheels . I have a 24 V battery made by SVolt that is 18 months old with good performance. There are a few forum members that are satisfied with the SVolt 51,2 V 106AH batteries . They also make a 220 AH battery . The large capacity batteries are build with the new blade cells .

My voltage was set correct from day 1 . No overcharging and now after 6 years 2 of my 3 batteries are starting to swell . They were all installed on the same day . The cycles are 884 , 772 , 815 . All com cables was installed between batteries . Even the difference in the cycles tells me this is not a good BMS . There is a hell of a alot of these batteries that start to swell on this forum. The system is connect to Sollarassistant and I could see when the first cell was starting to go out of balance . Supplier has disappeared. What is realy a good make of battery.

With my setup 4500 Watt panels is connected to the Voltronic MPPT and 3300 Watt on external MPPT connected to the battery . I run the Voltronic MPPT at a lower voltage and let the external MPPT do the bulk charing . The Epever MPPT have a beter setup system with better control . No voltage overshooting like Voltronic MPPT . I have more useable power and even get the batteries full in cloudy days .

@meetyg I did this preventive maintenance on my Axpert 5 years ago and sofar so good .

@Cyclic with my battery it was only 1 cell that went OVP and it was only the first few days it happend. This cell was out of balance but was balanced after a few cycles . Battery now in operation and cells stay balanced after 185 Cycles.

@James D try this company

@Bas84 5000W without heat sink

@Svolt Tech thankyou for supporting your customers . I had a 25.6v 2.71kWh s Volt installed also with to high charge voltage of 28.8v Bulk and 28.0v float. It was rectified but after only 32 OVP on no 3 cell . Running for 1 year and 147 cycles . Cells are well balanced now. Will this also void the warrenty .
