Kool Energy 1KW

[jolab]

I understand that this unit is the same thing as the Mecer / RCT 1KW models with different branding.


Very impressed with the unit - works like a charm and does what it's supposed to do - I can keep my entire office running during load shedding.

My questions are around the battery - all these units say that they have over-discharge protection. What exactly does this mean?

• Does it switch off the device if a certain % is left?
• What is this magic %?
• How does it know what type of battery I have - as this could affect the "safe" DoD.
  • Lead acid / deep cycle lead acid / gel / lithium-ion
  • Does it care?

Currently only discharging about 1 of the 5 bars each load shedding cycle but need to understand if I need to keep a close eye on the usage to stop damaging the battery or if the built-in "over-discharge protection" will sort that out for me.

I have read every (badly written) manual on the internet that I could find about all the models mentioned earlier and not a single one explains this function, even though it is near the top of the list of "features".

I have the Mecer version. Here is the manual, scanned it - have a look at the battery voltage parameters etc.

Google " Snadi All in One Solar Generator " on YouTube.

These units do indeed get sold with lithium/LiFePo4 batteries elsewhere if I remember correctly.

You are a star! My manual does not contain section 7.4 which describes the low voltage cutoff.

Also looked at some Snadi vids on youtube - Hindi is a bit rusty but it looks like you can actually set those thresholds by holding / pressing various combinations of buttons (b01-b04) - has same LCD control unit.

Won't mess with it till I have to but thanks for the Snadi heads up.

In case anyone is interested - Hubble S100A is a perfect lithium drop-in replacement for THIS unit.
Been running it for about 3 weeks - no need to change any settings.

NOTE : This unit looks similar to the RCT MegaPower but I don't think they are the same on the inside so make sure you do your research first before spending all the $$$

Hi Jolab, just want to make sure I understand your comment (maybe to temper my excitement....)

I've had this (Kool Energy 1KW) unit since Oct last year and kept it permanently plugged inline to power my modem, PC, a desk lamp and TV. Been working great but unfortunately the gel acid battery no longer lasts the full 2 hours of load shedding when powering all 4 devices and while I was shoppng for a replacement I was wondering whether I could upgrade to a lithium battery to help with DoD. Are you saying that I can simply replace the original gel acid with a lithium Hubble S100A? Or would I first need to change some of the (charging / inverter) components?

Correct - I literally replaced my gel battery with the S100A - no setting changes or part replacements. Works like a charm. The fan also still boosts as it used to when I put lots of load on the inverter during load shedding.

Sounds like your gel battery lasted about as long as mine Also got my unit in Oct last year.

But good to get a Kill-o-watt meter as well to ensure you know how much power these devices draw so you know what to expect from your battery.

When I am just working normally, I run 2x PC's, desk lamp (10w led) and 2x monitors (27" and 43") , total 270W - and I have run like that for 4 hours no problem (as expected / calculated). I run my modems (ONT) and mesh wifi using the Gizzu 65Wh for 6 hours silent operation.

Maybe I should start looking for old dead gel Kool Energy's and replace the with S100A's. Might be cheaper than a new one.

Hi Jolab,
I picked up on this whilst searching to see if it was safe to drop in a lithium battery.
Are you still operating your inverter and lithium battery without any issues?
Thanks

Still going strong - no issues!
I can only speak for the exact one I bought - S100A Hubble
