Solutions to load shedding

Here is mine

3.5 kva 12V Pure sinewave Mercer Inverter with MPPT (For future Use)
2 x 200mah batteries

Setup for the following:

My tank: Heaters, pumps, Ato, Lights, Wavemakers.... Tank will remain as if there is power

All lights in my house connected- I can use which ones I require
Fridge
TV
DSTV
SoundBar
Fiber router
2-3 Plug points for Power

Currently the load is around - 45%

I should get around 6-8, that will also vary pending what I wish to run based on the list above. My main intention was to keep my tank running without interruption, the other items are nice to have. I did not want anything near my tank, as I have a very specific way in which I have set it up.

A ups next to the tank will not work.

I have the same inverter and battery setup as @r0ckf1re . I use it exclusively for my tank. I don't have heaters running on it, the batteries wont last long during winter.

You mean you switch your heater/s off during a power failure ?

2 x 200mah batteries should do fairly well imo.
 
Yes and no. I have an external gas heater that I run my tank water by via an additional outlet on my return to the DT. The water stays heated and the return pump can run for days if needed.

Wow , nice setup , please show pics , and how do you regulate the temp ?

Besides the above - how would one power a 300w heater/50w pump for a day during a power cut ? ( talking winter - as I just lost all my fish to outbrakes of everything after an 8 hour cut and my gene wouldn’t start ?

How much does a setup like this cost.

Backup time is calculated using:

Battery AH rating x volt x number of batteries / load in watts.

So in your case 200 x 12 x 2 / 1500 watts (If you run at 45% load)

= 3,2 hrs .

BUT > to protect batteries you cannot use more than 50 % capacity .

So if you maintain that load > probably about 1,5 hr backup.

Keep your room temperature at or near your tank temp by running a gas heater in the room or using a fireplace if you have one, then it is just the 50W pump you need to care about.

Out of interest, I have the same invertor battery setup as @r0ckf1re, I run one heater and a wavemaker in the display, figure I can do without the lights, other pumps, skimmer etc for an hour or two. The heater draws 300w but only when on, I have it set slightly lower than the one in the sump so for first part of the outage it does nothing. During the one time I have used the setup (3 hour outage, during the day) I also threw a small pump in the sump to keep that water circulating. It ran the tank, tv, xbox and fridge for the 3 hours and made practically no difference to the batteries but it was summer, things would probably have been differentt had it been winter.

Even though I haven't really needed it I feel the investment was worth it since before I'd panic whenever the power went out, now it is just inconvenient.
 
I doubt winter would have made that much of a diff.

I have tested my setup and it’s far from just 1.5 hours.
 
I’m thinking Ellie’s 1200w inverter with a 250w heater and return. (30w).
Just so I don’t have to start gene in the middle of the night in winter.
Summer put wavemakers on.

Hi guys I’m looking for an inverter solution for my setup. I have something installed at the moment but it doesn’t seem to work and quite frankly the guy who installed it has disappeared. I’m not sure if I need to put in a whole new setup or if anyone can assist or recommend who I can contact. I’m on the East Rand so any assistance will be greatly appreciated
