Inverters

I've got requests to provide inverter backup (UPS) for several 3-phase motors. The motors are considered as critical operation and at present they're supplied by Eskom power are are backed up by generator so during power outages/load shedding the motors stop then auto-restart after a short time period when the generator supply has stabilized. This short downtime has been deemed unacceptable and the power supply needs to be improved to be uninterupted so the supply will be Eskom > UPS > Generator and vice versa upon Eskom supply restore. All the motors are standard 380-400v 4-pole induction motors and range between fractional horsepower and 2.2kW and are used fo…

Hello everyone. I have a Pylontech UP5000 coonected to a Kodak VM III (OG5.48) which when connected with a comms cable goes to low battery alarm mode even if the eveter is displaying voltage above 52V and the BMS soc lights are showing that the battery is full or almost full. The inverter fimware version is V41.17.7z. what could possibly be the problem.

I have currently got a grid tied solution which works great when the sun shines and the grid is up. Can I install a Hybrid solution first and keep my grid tied? In theory the Hybrid will trick the grid tied that the the grid is still up. When the sun is down the grid tied will switch off and I will het back up power from Hybrid system. Is my assumption correct?

Hi PowerForum Users, Looking for some assistance into a problem being experienced in a single phase parallel Axpert power system. 3 x Axpert 5kVA/4kW inverters setup in parallel. We have the communication cables and current sharing cables installed, and have tried to ensure that the AC input cables and AC output cables are equal length. While the Axpert inverters are in Grid mode, their respective load power can differ quite significantly – to the extent that the system has been tripping one of the inverters recently. However, while the inverters are in SBU mode, the load is shared very equally across all three inverters and an overload event has n…

This question is in reference to the ShineWIFI-S (firmware version 3.0.0.0) with the standard data update interval of 5 minutes (connected to a growatt hybrid inverter). Does anyone have any data as to how much data is stored locally, e.g. in the event of an internet disruption or the destination server (server.growatt.com) not being reachable? I'm assuming a TCP connection, rather than UDP, is made and as such data is acknowledged on the server before the data logger 'forgets' the data.

I have a 5kw sunsynk inverter. I have noticed that sometimes if everything goes on at the same time then it goes into the red. I know it can handle over 5kw for a short period. What happenes if the ac loads goes into the red for a long period?

Hi everyone Yesterday round about the time of the big storm in JHB, my SOC readings on my Deye inverter went haywire and since then it won't charge the batteries at all. The voltage reading on the inverter equals the float charge voltage, even though I can see on the batteries that they are 50% full. So it just sits at 100%. Any help please? Thanks

I have a Mustek/Axpert 5kva. When grid goes down I want to send a signal to 10 different linux machines to shutdown. They will start up automatically when power comes back (this is a bios setting) has anyone done something like this?

I'm planning a new system and I'm torn between the Growatt SPF 5000 ES or SunSynk 5kVA inverters. I would like to get some opinion and views on those 2 options. I have a prepaid meter, so cannot feed back to the grid. I was very much inclined towards the SunSynk option, because if it's ability to push excess PV power through the AUX port and feed the geyser, until I read on another thread, that AUX uses the batteries, which was a bit of a put off. In the beginning, I planning to use a small battery system - 4 lead acid/calcium Royal batteries with the setup and replace with Lithium batteries later. However, looking at the prices, the Growatt with a 2.4kwh lithium is very …

G'day all, Any suggestions for budget inverters (3-5kw) that support 48v batteries that have support for a generator? Sort of like the Sunsynk that has a load ramping facility at generator startup as well as load limiting, but without the price tag. Thanks in advance

.I have 1 UP5000 Pylontech battery connected to a Growatt SPF 5000 inverter The inverter sometimes go to alarm mode 20(BMS communication error ) for 2 minutes and reset itself after two minutes and operate normal for days . This has now occurred twice. What could be the cause of this error?

On my Axpert RCT - AXMAX8k, I upgraded main cpu firmware from version 46.02 to 46.05 and remote panel firmware from 12.03 to 12.06. System now running as it should..... using solar more efficiently, approx 40% more solar generated on demand ( before it stayed on bypass most of the time and blended power) now stays on battery mode for most of the day when solar output is higher than usage.

Hello Any repair/service centers for axpert inverters in cape winelands/capetown area?

3Phase advice needed. So we are between 2 fires on a 3phase installation using SunSynk. Either 2x 12Kw 3phase units or 3x 8.8kw units in a 3phase configuration. Question I have. If you go with 3x 8.8kwh units, and lets say one of The 3 inverters dies or goes offline for any reason, will this be considered as a phase loss? Will a phase protection relay help on a case of Inverter that drops out? Same goes for when the eskom side drops a phase, will this have an influence on the operations on the inverter(s)

Hi Guys, I just want to find out, if this inverter is connected to grid what is the max AC passthrough current it will handle? I know if there is no grid connected its 5kw but what can it handle while on-grid? Ive had this inverter for just over 3 months and today was the first time it had an AC overload issue and the grid was connected and on and I think the house was demanding about 6 kw, i thought it would just blend the rest from grid?

Hi My name's Pasquale, I'm italian. I ask support about an issue regarding "grid watt" or "grid current" to read from the inverter via RS232. I'm non a professional programmer, I've an inverter hybrid 7,2 kw (Voltronic brand) and I'm communicating via serial wit a simple program written in C# I can see the data with the QPIGS comand, but I can't see the grid current or grid watts. When I use QPIRI command there are the grid current but it is fixed (probably the target data of the inverter). This value is necessary for me because I would like design a software for the autoconsumption managing via a relay board. Acutally I can see "grid watt" on the M…

I need 5kw 48v control board to buy. +233244317829 is my whatsapp line

To prevent PCs restarting during the slight dip in power as the inverter switches between SUB etc, we have multiple small ups on our pcs. Say there's 10 of these. The input current rating on the sticker shows 10a each. That's 2.4kw each, 24kw just on the UPSs. Although the devices behind the upss are rated around 400w max. What would be a reasonable kw value to use in calculating loads for the inverters, obviously 24kw is way too much

I am wondering how the fault code 16 after connecting AC input into both inverters in a parallel split phase operation. I have exactly confirmed the wire connection and the communication connection with double D-sub 9 connecting cables. Although the fault code 16 means that "Input phase is not correct", the AC input L1, L2 and neutral line is connected exactly to each inverter from the grid. Therefore, I think that the firmware in my inverters may be affecting to this issue. The version of the firmware is 04 701 in each inverter. Dose anybody know where I can get the newest firmware?

Wanted to test the functioning of a Grid Tied inverter as input on the Aux port of my 8k Sunsynk with battery storage. Ran a temporary cable from my 2nd, Grid tied, 8kW Sunsynk into my Aux port and simulated a grid outage to run the batteries down to the 96% start up setting. It worked as described - the only problem being how the input power is displayed. On the flow diagram the Aux input shows only 2w when the input was actually around 800w. That is not the strangest. When I stopped the test by changing the setting back from Micro Inverter to generator, the Aux and the UPS displayed 32,700w and 33,300w respectively. It stayed that way un…

Hi Team, With the Sunsyk inverter can you do the following: Set a threshold for the battery and only charge it back up using Solar (e.g. have the battery discharge to 60% before switching to Eskom, but then only charging the next morning with solar) Have a second threshold that if there was load shedding and the battery drops to say 30%, then the battery will be charged by Eskom if there isn't enough solar Have the inverter prioritize having the battery at 100% before power any other loads

Can anyone tell me which setting to select between zero export to laod or zero export to ct I have a ct installed. Inverter runs the whole DB board. No special loads. We are not allowed to sell to grid. i read the manual and to my understanding it should be zero to ct, but just want to make sure as the electrician set it to zero to load. second question. On the home screen, I can see the load the house requires. I also see the load which PV generates, but its the same as the house load. When the house requirement goes up, so does the PV and other way around. Its as if you only see the PV which is needed. Is there…

Good day, I recently installed the above set up and would like some advice on the current settings which are reflecting on the invertor. Setting 03 AC Input Voltage Range - UPS Setting 12 Voltage point back to utility source - 46% Setting 13 Voltage point back to battery mode - 95% Would the above be correct/recommended? Additionally, I noticed my battery continuously discharges and recharges from 100% to 95% , then back to 100%. Takes about 6 hours to discharge to 95%, then about 15 min to get back to 100%. Is this normal and has anything to do with setting 13 by any chance? Appreciate any assistance. Thanks

Hi guys I have a deye 5kw inverter. I had loadshedding and it took 6min before the inverter battery kicked in? Anyone know how can I fix this? Where it will be a seamless change over?

Hi guys, anyone that can point me in the right direction to get the latest firmware file for my kodak og7.2 inverter. It's currently running on 45.07 and I have another 1 running on 90.15 Thank you
