JannieM Posted July 21, 2020 Share Posted July 21, 2020 Helo, I have 4 Narada Lithium Ion batteries 100ah connected on a Axpert 5 kVa inverter, what would be the best charging current be for the pack. Quote Link to comment Share on other sites More sharing options...

Welcome to the forum Jannie.. Thank you, yes I have, 0the reccomended charging current is 20a, but i have 4 of them and I forgot to say that I have 2 axpert inverters in paralalel as well Parky 1 Quote Link to comment Share on other sites More sharing options...

JannieM Posted October 1, 2020 Author Share Posted October 1, 2020 Hello, just another question, I have the amps set at 80 now, what should the back to discharge voltage be, i currently have it at 56V, and the back to grid voltage at 45V and what should the bulk and float charging wees.

Quote what should the back to discharge voltage be, i currently have it at 56V, and the back to grid voltage at 45V and what should the bulk and float charging wees. Despite the manufacturer recommending 54.0 ± 0.5 V, I'd go with the voltages that work best for Pylontechs (which are also 15S LFP). Quote Link to comment Share on other sites More sharing options...
JannieM Posted October 4, 2020 Author Share Posted October 4, 2020 Thank you Coulomb, I did the settings as said, at the moment with the sun at full steam the batteries is floating at 51.9V but the SOC on watchpower sais it is charged at 52%. Isnt it suppose to be 100% now? Quote Link to comment Share on other sites More sharing options...

JannieM Posted October 4, 2020 Author Share Posted October 4, 2020 What is the latest firmware for these inverters, or do we have the latest on? Also do you have a whatsapp number where i can contact you Quote Link to comment Share on other sites More sharing options...
SYC Posted October 4, 2020 Share Posted October 4, 2020 (edited) The correct settings for that batteries are (supplied by supplier): so 40amp per battery so 80amps on both Inverters You have the Axpert MKII 450V inverter just for future reference. Latest firmware version is 71.82 I think Edited October 4, 2020 by Quwatush Shams (Suly) Parky 1 Quote Link to comment Share on other sites More sharing options...
Coulomb Posted October 5, 2020 Share Posted October 5, 2020 Yes, the latest firmware I've seen for this model (the Axpert MKS II) is version 71.82. Quote Link to comment Share on other sites More sharing options...
Izak Cronje Posted December 21, 2021 Share Posted December 21, 2021 Hi, Please confirm settings with 1 off 100 AH Narada Lithium Ion Battery on an AXPERt 5KVA invertor. There is no utility - we only have Solar and Generator to top up if solar not enough I need the following settings: Program 2, 12, 13, 26, 27, 29 Thanx Izak Cronje Quote Link to comment Share on other sites More sharing options...

Nhlanhla Posted August 16, 2022 Share Posted August 16, 2022 Hi Team, I recently bought the Narada 48V 100AH Lithium Iron Battery and the Hybrid inverter 5000VA but the 2 do not talk to each other. Which inverter is compatible to your Narada 48V 100AH lithium ion iron battery? Best regards, Nhlanhla from South Africa Quote Link to comment Share on other sites More sharing options...
