Thats 2 units of 3.4kw lithium Sent from my GT-I9500 using Tapatalk

Hi guys id like to know more about lithium ion battery packs Im using about 24kwh /24h About 10 hours on solar 1hour on battery 13 hours eskom I have 12x255w@24v panels 1x expert 5kva and 12x170ah@12v 3 strings @48v During day time running on solar my inverter set to only use 20%from battries (dod) So from about 6/7 o clock switch to grid till about 8 /10 in the morning (depending on weather ) Was thinking of getting 24x2v@ +-1000ah Will be about R100k Heard about lithium ion and thinking maybe the way to go (6.4kw lithium bank) @R70k 1 square meter and 70kg Instead of (24x2v@ +-1000ah) 6 square meters @ 2400kg But imnot sure of how it works with lithium ion Acording to wat I've been told 6.4kw lithium = 1000ah lead acid Please advise Sent from my GT-I9500 using Tapatalk

Could it be micro inverter panels ? Sent from my GT-I9500 using Tapatalk

Hi guys dont find this onsite but wanted to know is it worth it to spend R100K for a 48v bank made of 12x2v@900ah Compared to R50k 48v bank made of 16x12v@230ah (920ah) Thanks Sent from my GT-I9500 using Tapatalk

Not sure about peak /off peak rates But different rates according to usage eg : 0 to 50 kw @ X (R0.87) 51 to 300 kw @ Y (R1.11) 300to 600kw @ Z (R1.78) Sent from my GT-I9500 using Tapatalk

Oki after two weeks of using aicc to monitor whats going on Set my inverter to only use 20% then switch to grid Question: Is it better to switch to grid only running on grid only charge with solar next day (grid usage average 10 hours ) X kwh Or switch to grid and charge from grid set @10A utl charging (Grid usage average 10 hours ) +- 4kwh Sent from my GT-I9500 using Tapatalk

Disconnect ac in and ac out switched off pv and battery Only put on battery inverter dose click about 30 seconds after i on in Stays on Put pv on relay clicks again to start charging about 30 sec after i on it Inverter stays on with No load Sent from my GT-I9500 using Tapatalk

My inverter says mercer on it I got a Mecer AP1103 USB To Serial (RS-232) Converter Could it be com setting on the laptop/pc The only thing i changed on pc was com port it was reading as com 7 changed it to com 1 Sent from my GT-I9500 using Tapatalk

Thanx awesome to be here 1 ) I put off inverter @inverter switch 2) put off all isolators Eskom in off Pv off Output off Battery off 3) put on battery Plug in rj45 /rs232 Switched on inverter 4) extract zip file Opeded reflash tool 5) click update and yes Runs +- 30 seconds Clicks inside inverter Then gives error ( cannot open serial port) 6) inverter unresponsive untill i dis connect battery Sent from my GT-I9500 using Tapatalk

Hi Gnome did you come right if so wat was wrong@coulomb I'm having same problem Sent from my GT-I9500 using Tapatalk

Sorry my mistake[emoji85] ( edited ) im running 2xfridge 2xfreezer lights (led) 2xtv Decoders Chargers Laptop thats why 800w Sent from my GT-I9500 using Tapatalk

Thanks paul Firstly i started my solar system as a back up 4 load shedding (2×80w panels 1x105ah deep cycle small pwm charge control and a led stripes in every room ) Voltage drop and wrong wiring got me to up grade to 4x100w+2x80w panels 2000w 24v inverter 1x so called mppt 40a controller 12x 6v golf car batteries "2nd hand " wired in to db with switch over switch mainly used solar 4 lighting Batteries gave in due to poor maintenance and age im guessing Found batteries @china mall 180ah 12v i think gel 600mmx300mmx150mm +-50kg Also bought some @auction Got total of 14 battries 2 running 12v lighting 12 were connected to 2000w inverter started connection all lights and 80% of plugs no fridge or hi power appliance Was using more than i was getting of my panels Bringing me to last upgrade 12 x 24v pv 5kva inverter built in mppt Now only geyser on eskom when needed solar collector keeps water hot 80%of the time Solar system connected 100%lights 50% plugs inc 2xfridge and 2xfreezer inverter shows watts being used around 800w not all the time but i still wanna connect a 3rd fridge and freezer So i toke 800w x24h =19kwh per day rounder it off to 20kwh +50% for being safe got me to 30kwh If i can log my data will be able to better understand wat im using and wat I'm charging Sorry 4 long story 1) i have a system running 2) not sure hopping to be able to get tru the night without killing battries 3) no reason cutting cost using minimum eskom power Sent from my GT-I9500 using Tapatalk

Good morning sorry 4 being unclear I need help logging data over network Also Finding 2v batteries @good price And Advice on working out battery bank ah and amount of panels needed to provide +- 30kwh /day Thanks Sent from my GT-I9500 using Tapatalk

Hi guys Mohammed in limpopo (0510) I'm new to solar looking to go off grid @the moment i have 12 x 180ah 12v 4 x12v =48v @180ah 4 x12v =48v @180ah 4 x12v =48v @180ah Total 540 ah @48v 5kva inverter Mercer eskom in solar in batteries in 220 @ max 4kw out 12 x 255 24v panels +24-+24-+24- +24-+24-+24- +24-+24-+24- +24-+24-+24- Wanna Use about max 30kwh/day off grid Please advise Need help getting invertor on network also logging data and Was thinking about getting 2v or 4v batteries Sent from my GT-I9500 using Tapatalk
