Kudos to your set-up! How do you run your 1500w water heater 24hrs ? What's your battery bank capacity and solar capacity ? Remember you stated you had no space on your roof for the non pressurized solar water heater but if you can work on your piping, you can use a pressurized solar system .....

Saipro:


I do have a different approach these days and it works just fine for me. And my Ariston 50L tanks can retain the water hot for 3 days (2 days with use).

pranil:


Nothing special.
The 4 AC's are inverter Ac's ( 1 LG 22,000 BTU , 1 LG 18000 BTU , 2 x diaking 18000 BTU) - On power save mode they consume less than 700 watt ( sometimes 300 watt) each - the AC's are power controlled by a cheap aliexpress regulator so if switched on accidentally in turbo mode ( 2.5 KW each) the power controller gives audible alarm and after 60 sec switches off the power to teh socket

The whole setup plus my microwave + 1.5 kW water heater is connected to 2x 5 KVA Ipower on 400 AH battery bank with 2.5 KW solar PV and 7.5 KVA DG ( 3 phase 50 amp 48 battery charger)

The Ipower are controlled by a software ICC which changes them to Solar mode between 9 am and 4 pm- If the SOC drops below 47 V DC the ipower come out of solar mode and change to Nepa

The DG comes on if the SOC drops below 70 % and switches off automatically. ( or 12 pm in the night even if they are not full) This is mainly useful in the night if there is the power failure .


The rest of the house is on seprate 5 KW inverter +lithium so I am not worried if the DG does not start and the batteries are fully depleted in the night as I can attend to them if required in the morning

This setup allows me to use the parlour Ac's in the daytime directly on the PV panels ( or bedroom at weekends and on batteries or DG in the night

I have used 31 ltrs of Diesel since 1st Aug till date - including the maintenance run once every 2 weeks .


Hello pranil,

I am interested in the power regulator/controller. Can you provide me a link to the product so I can order??

Thank you in advance

Urghh, this place don dey dull again !!!

DMerciful:
Yeah... We need new high tech solar stuff ....

olagunju2000:
Good afternoon houese.

I finally got the Magnum PT-100 charge controller with the remote monitor ME-ARC50. However, the monitor can only be used with a Magnum inverter connected to the charge controller.

Please has anyone found a workaround to this in the house?

Right now I am only able to view PV voltage, PV power, charge voltage and current. Monitor will be needed to view logging data.

kiekie1:


Haha! That's money for high tech or latest power stuffs... Upgrading to LiFePO4 batteries like 48v- 360ah / 750ah / 1800ah , tesla etc ain't really easy !

kiekie1:


Sir, that ain't what we wer debating! Its all about having hot water continuously with rest of mind , and also energy efficient .. The example I gave about 72hrs is more or less like a theoretical example if we have very DULL WEATHER for 3 days but you know there must be sun to aid in warm water if not totally hot as the solar vaccum tubes are sensitive ! If you have a mighty battery bank of 48v 600-1000a upwards , you can always give your old ariston 10L electric heater a shot .. I wont really advice same if you are just managing 48v 200a or equivalent , you must be ready to replace batteries due to abuse because hot water is like an addiction .. Meanwhile, not all men/breadwinner have time to keep controlling/monitoring water heating affairs at home if connected directly to a miniature solar system et small battery bank.. Mr Pranil system is automated-controlled .. Cheer's

Good morning house.

A friend put on his 5kva generator and switched on the change-over switch with the inverter being the only load on the generator.
He heard spectacular explosions and smoke from the inverter.
About 6 FETs are obviously damaged, the rest are also shorted.

Did the damage have anything to do with the fact that the inverter was the only load on the generator ?

Will replacing all the FETs bring the inverter back to life/Could any other components have been damaged besides the FETs ?

Thanks everyone.

Braaad:
Could you post a connection diagram,
that would help to determine if you were mistakenly back feeding the inverter.

The inverter being the only load on generator is not the cause of mos tube damage.

dejidotun2000:
The inverter was not being backfed. It was installed about 3 years ago and no modifications have been made to the wiring/connection since then.

Sh!t happens and electronics can just go kaboom for no good reason.
But you need to give it to a seasoned electrician , , ,
Do not attempt to change the Fets on your own . . because in most causes;
the shorted Fets creates a short inside the gates . . and this damages
the circuitry that drives the gates . . .
Change the all mosfets and connect the inverter;
and you will hear another kaboom ; back to square one.

N.B.: Be careful when you handle circuit boards that contain capacitors; they can store power high enough
to deliver a fatal electric shock; even when they are powered off (especially when the unit was just disconnected; without discharging
the capacitors)

Many thanks sir.
Can you recommend a competent technician to handle the repair ?

pm me if u r in lagos

Saipro:


When my water heater setup clocks one calendar year, I'll give the house my own review. It works fine for me, sunshine or no sunshine. And trust me, it is very battery friendly. The don't-try-this-at-home clause is the only reason I haven't published my report to the house. Besides, it's not to be attempted by beginners.

My brother you took the words out of my mouth. So far 2weeks after my upgrade no problem so far. Even set the timer on my fridge earlier now 9am. While water heating by 12 pm. Still studying the whole system. Like i said earlier a day of heating last 3days..

bodeface:
Guys,
Anyone with experience on the Kung Long 12V, 200Ah Batteries, how strong are they, how long have you been using the battery, I am considering buying one but exercising restraint due to previous experience on some brands.
Thanks for your helps!

DMerciful:
He can convenient change the fets. the gate resistor has such a high resistance that failure to the driving circuitry is unlikely. i have change my small inverter twice and i have spares for the next failure . To limit the chances of electric shock from capacitor, put on the inverter after disconnection from mains to use up whatever is stored in the capacitor besides capacitor will give u and unpleasant shock at worst...nothing major

DMerciful:
Heater last for 3days? what brand of heater is this?
