Mecer 2400VA Inverter (Community Support)

I would start with a S-100 hubble battery and forget about lead acid. Then you can do whatever and should last 10+ years.

Technically speaking, with the Li-Ions on constant float charge they can also hurt a bit? I've seen phones swell up when on charge 24/7, so their BMS wasn't enough for charging all the time. Not sure what the Hubbles would do, but interested to know.

You want the oke to put plastic on his gas burner?

But then won’t you be wasting electricity keeping it charged?

Nope not really, it uses about 10 to 50w so like a light bulb.

Another question, if two TVs and home theatres are far from each other. Will you need extra extensions or another inverter?

Either, your choice. One just involves tripping over wires: take your pick!

It shouldn't be an issue. If you really concerned loadshed yourself once a week.

float use less power than your plugged in but unused cell phone charger.

Besides Lead acid does not like being below 100% not even for a second and they do self discharge so its good practice to keep em at float.

Better than buying new batteries, and like @Grouter said, a UPS is so you don't get left in the dark when the power goes out so your stuff should be connected to it permanently.

Depends on what you want to achieve to be honest, the nice thing about the mecer unit is, if you've got it online when the power goes off, it just remains running like a UPS.

The thing that calms my mind is that it floats at 13.8V. Fully charged hubble is 14.4V.

Which is a good thing as your LiFePO4 on the other hand dont like to be full

How much does a plugged in cell charger use?

Are there better batteries one could buy for a plug in solution?

I really don’t mind being in the dark for 5 minutes to go plug in the inverter device, then power up the necessary appliances.

How much power does a small transformer consume when plugged in but not doing anything?

A typical home probably has five to 10 transformers plugged into the wall at any given time. It turns out that these transformers consume power whenever they are plugged in, whether they are connected to a device or not.

LiFePO4 dont like to be full but has a higher rate of self discharge, ie: will have no negative effect to leave unpluged but needs to be topped off once in a while, for in case you need to use them.

End of the day I would still leave them plugged in. The R's you think you saving is not worth the effort. If you really wanna save $$ maybe look at Solar blending inverter* instead of a Mercer.

Edit: fixed a word.

Hi there,

Question, can I switch the charging amps from 10 to 20 at anytime, like when its charging or do I need to switch off the inverter and unplug it to switch to 20 amp charge?

Anytime.

 

[AlphaJohn]

Anytime.

i just did that when i got home, was busy charging from a 12:00-14:30 slot. Filling it for 20:00.

only diff was fan went notably louder...i can now hear it from anywhere in the house and my V shot up to 14.3 per battery.

One hour in and it already dropped to 14.0 so should be ok....

 

[Steijn1]

Anytime.

Where is the switch to go to 20A?
Thanks

At the back of the inverter.
