Ordered from Solarwarehousesa on 6 April 2023
I tested it with a loose 6.6ah lithium battery to check that it switches on before i installed it.
It switched of after 2 seconds.
Thought maybe battery is to small. Then
switch off and on again then it stayed on. It scares a person.
I installed it replacing my main seperate 4kw inverter and 120A WRND
solar charger. The WRND charger would switch off (Shows off) when low
battery and never switched on by itself again. I had to use a seperate
charger in parallel with WRND to up batteryvoltage and after some time
the WRND would recover. WRND support never responded.
The conderenergy has 2 bottom fans and i have yet to see them stopped
when nighttime. That means it is draining my batteries unneccassary
during the night.
The fans are fairly quiet when nighttime.
I will post more experience when coming across new flaws i find.

That looks to me to be a Voltronic Infini clone. I don't know these well, so I don't know what model it might be copying.

AFAIK it cannot export to grid but this was the 1st brand i saw with dual back up outputs which I kind of like to have a 2nd output for real essentials and also different voltage settings on their 6kW 48V model. 

I have not seen any specs on the 24V unit or any at the on line shops. But yes one does not look at all inverters unless one is shopping. 

I started the unit this morning but first checking panels voltage then inserted fuse. I was far from the inverter and it was cycling on and off i could hear. I switched the main switch off and on and then all looked normal.

I am using it offgrid . Did a DIY install but i have an engineering qaulification.

I was so excited to see it started a woodwork spindle with industrial motor without hesitation. I could never start it with my WRND charger because the damn charger would switch off when batteryvolts went low.

Thereafter installed the wifi addon. Will post pics later of the wifi app screens

I saw in the specs the no load power used is 30w. So the fans never switch totally off. The fans are very quiet.

Could you perhaps place a pic or link of the WRND charger you mention on your previous unit used. 

How can business people sell a battery charger that stops charging when battery low voltage and never recover.

I bought the WRND 2nd hand and very  quickly found out why it was being  replaced. There was no answer from the support on this charger.

Conderenergy s-2435  --hiccups

My batteries gets depleted every night as the inverter fans are running continually non stop -- 30w no-load power usage according to specs

My previous inverter 4kw did not deplete the batteries.

However in the morning when the panels start to get some power the inverter cycles on and off continuously until i pull the breaker on the solar panel wire connection

I have adjusted some settings yesterday morning but the same happened this morning.

The priority setting was SBU ---default is SUB- but this is an offgrid install

So this morning i changed to UBS priority -- will see what happens tomorrow morning.

The inverter basically switches on but there is not enough solar charging yet and it switches off again.

I cannot think of any means currently to cause a delay in the inverter switching on

The solar charge voltage is min-60v  nominal-240v and max-500v

So if i was able to adjust the 60v higher it would switch on when there is enough power from the panels mainly to drive the 30w fans

Battery voltage is 22v in the morning- it only switches off at 20v.

No matter what i tried the only way to stop the inverter cycling was by disconnect solar panel wire.

As with all my previous inverter experience they always lock you out somewhere.

Never full control

Somehow I am making some assumption which you can correct. 

As you are off grid the 1st thing to consider is to switch the inverter off if you can to reduce the drain from the fans. With always on WiFi one can use the low voltage 5-32V DC Sonoff to switch the on/off switch of the inverter. This is if the switch is a stay put switch and not just a trigger. If a trigger one can use the inching setting. 

Next will be a extra battery to be able to supply the load and fans during the night. 

If you can be without the inverter on via the above Sonoff and inverter is off you can get a external MPPT like a Epever with lithium setting to charge the battery when there is sun without affecting the inverter. You can then remotely switch the inverter on say 45min later than it is switching on to allow some power into the battery after the night time discharge. 

Lastly a question. Your reading show PV as around 400W. Increase the PV with another panel. 

Does the battery charge to high SOC before sunset? What size is it? 

In your case it is self power as well as the 30W of the fans

Hi Scorp007

As said previously i am an Mech/Elec engineer

However the advise you gave is 100% correct.

Switching off the inverter does not switch the fans off. (i had a similar situation with a 3kw MECER hybrid (non-sinewave) inverter-eventually gave it to my brother for free)

I have 6 x 325w panels in series

I attached a screenshot when tested inverter output with a 1.5kw load

The app kw readings are incorrect too low 1.1 on the app is actually 1.4kw on the inverter

I was in the same situation with my WRND charger whereas i had to use another charger in parallel to bring the voltage up for the WRND to switch on.

I bought this Conderenergy thinking it is working 100% in all scenarios to actually eliminate me watching the charging every morning.

Now i am back to square 1 after spending about R6000.

I have contacted the supplier with regard to this error

Being engineering minded all equipment should have been tested fool proof under all conditions to a satisfactory level.

Be assured others will run into this same situation - hence this post to help others.

I am busy systematically changing my batteries over from SLA to Lithium as the SLA gets old. (i check the batteries with a thermal camera)

 

 

Yesterday -17-5-2024    i changed the panels to 2 x strings of 3 x 325w in parallel for a test reasoning more amps at 60v when recovering from low voltage shutdown.

The inverter did not like this at all and gave more errors.

So i changed it back to 6 x 325w in series

Then the wifi (SmartESS WiFi Plug Pro) showed offline so i could not see the graphing.

It took me half the day to get it online again.

What happened was the ip address changed of the wifi plug pro most probably by my router.

I had to delete everything on the SMARTESS app and create a new login and add the device in the new login. (youtube.com/watch?v=HqVQ07IHhLk)

I could not recover the graphing on the old login.

No data was lost as the logger was working while it was showing offline in the app.

The support from Solarwarehousesa was quick to give general comments and critique but no solution was given at all to this problem of low voltage restart on/off cycling in the mornings.

I deduct therefore i am one of the very first who bought this model and having this problem.

My answer to support was the inverter needs to gracefully restart after a low voltage shutdown in offgrid mode which can only be done in software/firmware update.

Hopefully they take this up with the manufacturer.

One solution could be to insert a timer on a low voltage recovery restart or make the min charge voltage of 60v adjustable upward.

Personally I would not try and run on a 3 x series string with 325W panels. Although the MPPT range is 60-500V it is common that you need more than 60V as a starting volts to get the MPPT to kick in. 

Without seeing that the inverter does not want to start when the voltage is high with 6 x series I don't think it's worth tinkering with starting at 60V and moving it up gradually in order to start. High current at a low voltage would normally not get the MPPT going. 

It is normal if a dongle could not use the WiFi that the data during this time is lost. The inverter normally keeps this data for the day but what could not be sent to the cloud is normally lost. Refer to my post under the winter PV production when my data ran out. 

If the inverter is faulty and not operating as it should ask for a replacement.

The inverter is working correctly except for in the mornings when it starts charging cycles on/off continuesly because the batteries got depleted and inverter switched off due to low voltage at about an hour before sunrise. I then have to  switch off the solarpanel charge wire supply at sunrise which is the only way off stopping the on/off cycling. Then wait another 30min and switch the solarpanel charge wire back on. Then the inverter will start perfectly normal.

The supplier suggested setting it to SUB priority and add some batteries.

All other things considered i am happy with the inverter.

Luckily you know what you need to try and do to have a higher SOC in the morning(switch inverter off 30min earlier via setting) to prevent the on and off and/or to get more battery power/load reduction. 

Hi, power off in area and batteries went flat during the night

in the morning I have code 09 with solar ray @ +200, not kicking over. No power yet

update, power is back but code 09 still appears 

Can I please have a manual for conderenergy inverter,model S-2024, I am experiencing the same issue with batteries being deeply discharged every morning
