And my setup that wired into the DB? I can't switch off cause then I have no lights or TV :unsure:

Should I just self loadshed once a month ? drop to say ±50% ?

i assume no solar

if you have lithium and changeover can just flick it over
and switch off the inverter and actually save some power

know a guy that had a sunsynk in his holiday home
and just the standby usage was adding up to 2.4units a day
so at current rates was essentially paying R225 per month for nothing

i told him he can just do a top up once a year
he was worried that it may go too low if they aren't there to check from time to time

he opted to install 4 panels
to have zero bill the pool pump runs mid day

this is the no brainer imo as suddenly it generates savings

if not holiday home
the panels will return their cost in a year dependant on inverter a person can also approach this
in phases

with 12/24v you can start with a single panel
with 48v unfortunately you gotta do 4 50v 72 cell panelor 5 41v 60 cell with the 120v startup voltage of mppt
if you have 90v startup 3 panels

lead acid just leave as is

if lithium
can just set the charge/float voltage lower
i would not cycle it


maybe set it to nominal voltage
ie let charge and float match nominal ie 51.2/48/25.6/12.8 whatever your system is

discharge a bit and let it charge back up to that voltage
that way it will keep it not full

naturally you will have less backup in case of power failure
can find a voltage between nominal and lets say 2.5% lower than float
51.2 -- 49.9v
48v -- 46.8v
25.6 -- 24.9 to 25v
12.8v -- 12.5v

to keep it away from full and finding the balance of still enough backup for power failures

Thanks. This is the Mecer thread. Can you select to what percentage your batteries are charged on a Mecer? And I just have a normal 200AH lead acid battery.
I have it switched on at the plug, but the switch on the unit itself is off, thus it will not draw from battery when power goes off.

Lead acid is fine if kept at full charge, so leave it plugged and cycle to not less than 50% discharge once in a while.

Bought 2 x 200ah lithium. Just before load shedding stopped. Now I miss loadshedding....

Yea the first lithium cells i bought load shedding also disappeared for months

A person feels damn that money could have been used way more productive

Unfortunately i think the drastic year long stints of shedding is behind us
Maybe we will still get the odd here and there

If eskom gets the 30% it is over

For many holdouts those that felt ok i can live without tech for 2 hrs we will braai for supper

the pain of the bill will become the incentive they never had to get
Into solar

And for those that the ROI window is too long same

I’m taking one for the team and doing fokkal with my 2 x 100Ah LFPs and just leaving them on 13.8V float for the next 10 years.

I ended up going full solar, and keeping my 2x 24v 100ah for a rainy day, literally. I am having them wire it into the generator port on the House inverter and will eventually write some automations which will trigger importing the old lithiums into the house. Probably finish that in 1-2 years lol
 
So lightning killed the Mecer amongst other things, and Insurance paid out. Now since we don't have load shedding it is not first on the list, but I think I will replace it just for incase of load shedding or other power outages.

I will spend more or less the same R2,5K. Only things run on the inverter is Routers/fiber system, tv, garage door motor and 2 lights. I have a 200ah lead acid battery in great shape, so not going to replace that now.

So question. Should I just buy another Mecer. Or will these be beter.

This seems to have Lithium compatible and is pure sinewave.

Or something like this. Would it work with a Lead acid battery? Can you plug a solar panel in. Do it need to be connected to your DB( I dont see a plug on it).

The second one seems more efficient and more features like mppt solar, yes LA battery should work.

yea take the second one, can ad a line with a plug input and a line with multi adapter as output
and run it like a mecer, just head the max load of the plug ie 16A if bypassing when overloading

buying something that is solar capable is a must if spending mony on an inverter imo

cause that helps reduce eskom bill, and actually returns the expense

LOL there is so little stuff on that inverter, not going to save any money. I am more interested in putting a solar panel up with this, for that 2-7 day power outages when a substation blows. Then at least we can have internet and charge phones and stuff with a solar panel charging the battery.

I don’t think 1000W and one gel battery is going to max out a 16A multiplug.

I would start putting money aside for a 100Ah LFP for when the gel battery dies.

many of these inverters have a bypass function and will switch to bypass the inverter portion and draw power direct from eskom
on my 5kw kodak i have bypassed 8kw

you lose the ups functionality
and thus if you go into bypass mode the limitation of inverter disapears and then the plug limitation can come into play

have a friend that had a cleaning lady plug in iron vacuum cleaner etc cause the plug happened to be more convetiently located
so do the setup for the dummies that might subject it to what you havent planned for while not there

Okay, multiplug can handle vacuum cleaner.
