Mecer Inverter

[wingnut771]

I have heard some say that in rush can pop a device

Ie if the caps are drained , when you first connect the battery you often get a spark as those caps soak up energy

Often it can pull loads of amps

The correct way they say is to attach one wire then have a resistor between the other wire and the terminal to charge up the cap slowly then remove resistor and attach the cable

I don't have a resistor lying around , so
what i do is just tap the second wire and deal with the sparks (have sunglasses or safety glasses on) then when it does not spark anymore it means the cap is charged up and i attach the wire hoping that not a lot of amps can flow with the taps ie not a proper connection

Have heard others say they have connected and then flip the battery breaker and let it flow without problems

I maar heed the old wifes tales in case
it isn't just a myth

If that's the case then this will be the first case I've come across.

@dazza1967

Does it have an inline fuse on battery lead ? Or maybe a overload pop out button on the back of the machine

Maybe if there was an accidental touch a fuse will pop or pop out button happened

I would just disconnect the power cord switch the battery breaker off and on then attach the eskom cable again ie reboot

Other than that no ideas

Yea i have seen many videos of people having the arc or connecting the device without popping

Hence why i say i do the superstition tap ,i think it may be a myth

The one daly bms i had the easiest way to jump start it was to use the cells power on the outside of the bms ie , plier touching the two terminals ie battery negative to bms outside negative , i always told the family the sound is coming relax it is all good

Dreaded that arc

I naturally did the spark thing many times before hearing the story

When I do the tap, I tap it on the screw head and then remove it from the terminal so the arc doesn't damage the surface of the terminal.

How is it possible to read 13V on the one end of the cable and 8V on the other end?

I just took the unit for further inspection, and I was advised that the Mecer SOL-I-BB-M1 is not lithium-compatable.
By all accounts, that is not true, according to this thread.

They always say that so they avoid liability so you can ignore that. You should take it for inspection with the old lead acid battery just to avoid any confusion.

I thought as much.
Unfortunately, I didn't swap the batteries myself. Something has happened to the unit during the swap.
Thank you for all your advise. Much appreciated

What lithium battery can I use in a SOL-I-BB-M1 - having the following specs: Mecer 1kW 12V pure sinewave Inverter with 1x 100Ah deep cycle gel battery.
Has anyone done the swop.

Have you done the swop? Did you do it yourself? Just want to check on how to access the battery easily (once unplugged and switched off)

 

[garybing]

Hi @wingnut771 , kindly see attached - i am not sure if it is the pin next to the white one. i accidentally pull it out while take the whole case out to remove the battery

Hi, I have the Mecer trolley inverter (SOL-I-BB-M1) when you removed the battery, after unplugging and switching off, does one then undo the screws at the bottom on the short sides to move the top assembly to one side? Just want to make sure i dont damage anything.

My battery was flat so I wanted to use a standard charger on it to see if that would help. The trolley box is a real mystery. Take off the back panel. Undo the 6 screws 3 at the bottom if each side panel. Remove the lip at the back 3 screws. Remove the 4 screws holding the battery in place and then try slide it out.

I've removed every screw and undone every panel i cant find an easier way of getting too the battery. Good luck.

Yea i woud make a small roll of insulation tape by rolling it back onto itself

And tape up the wires as you remove them , don't want them to touch something while you try and wangle out the battery

Even if the battery is out and power is disconnected there is some capacitors that can discharge and make a spark

And tape over the terminals

And at what point do you say maybe running the battery on external connection has a bonus i can't short something out while changing the battery , and won't have to ever deal with jump start scenarios, and have some extra capacity from the lead acid

In case anyone else was wondering, or happen to come across this thread, I've upgraded my Mecer 1Kw trolley with a REVOV 100Ah 12V LiFePO4 battery and everything so far has been running 100%

The integrated BMS also makes a world of difference in regards to monitoring the battery.

Yours a SOL-I-BB-M1 as in the image?

Not sure about that model number(?), but yes it looks exactly like that.

Good morning. I trust that your inverter is working "better" than before after you replaced the lead acid deep cycle a lithium battery. I did the same as it was a simple swop = problem free and still going strong. Bought a REVOV - 100Ah 12.8V - 1.28kWh Lithium Battery for R6,240.88.

Good morning. Just a question to confirm - After installing the lithium battery, does you "smart" cooling fan run continuously or only when the battery is charging after use?

 

[Katjie]

hi

Hi

I struggle at the beginning, I unscrew the whole unit… turn the whole machine upside down just try to get the battery out.

So in the end,

1 technically just unscrew the “silver holder plate”;

2 wear a glove for preventing your hand get cut;

3 put in a silver flat stick at the bottom of the battery; just to try lift the battery for you to drag it out; (it really heavy)

4 unscrew the negative, then the positive.

5 then put new one in, then let the machine recharge fully before use.

If I recall correctly. Only when charging. And only when using “hectic power”.

But if it only used like light bulb / pc - it quiet.

@Katjie if you are still on the group, do you have an update on the status of your REVOV after the replacement of the gel battery
