Barezzi:
Nice one... but check the bolded again. A typical 30L water heater takes about 15 to 20 minutes to reach the setpoint.

I don't know what boiler you have, but mine takes longer. Maybe it has something to do with the length of the piping involved and concurrent use. The heater supplies 3 rooms and serves 4 people on most mornings with children and wify sometimes letting the hot water run off because they are multitasking.

Trippledots:


If 520ah is roughly equal to 80% then your battery bank capacity is less than 1000Wh. How does it compare to 12 units of 12v/200ah ~= 29KWh bank though?

I have no idea how you are calculating your figures but 520AH at 48V is about 25KWh.

I was thinking a 30L water heater will take more time to heat up, my 30L Ariston can take almost 40 to 50 mins to boil, i set it at highest heat setting and its rated at 1,500W.

I have read through the response and one thing I see you failed to ask was weather condition before arriving that the panels are fake. I feel an input voltage of 72v and charge current of 35A is good for a flooded lead acid battery. Knowing well that the battery the poster mention requires 12A normal charging current, so getting 35A should be able to charge the batteries very well. Unless he is drawing more than required.

TechGeek777:


If the watts stated here is per hour, the panels are definitely fake.

If it's comulative, the batteries should be checked.

In all contact your installer.

Bragging Time

The last few days have been very cloudy and raining in Ibadan. So, my solar yield has been poor.

This morning I discovered that I have taken 520AH from my lithium battery bank which is about 80% of my total.

I sat down to do the calculation. 520AH at 48V is like draining 12 200AH 12V lead acid batteries to zero. However, given a 50% DoD, already above what is recommended for Lead Acid batteries, I would have needed a bank of 24 200AH 12v batteries.

And even then my system would have shut down because my pumping machine drawing about 2KW and my water heater drawing about 1.5KW still came on at 4:00AM and 5:00AM respectively. Pump for 25 minutes and heater for 90 minutes. Voltage would have gone down low enough to trip the inverter.

If you are not using lithium batteries, you can not appreciate its resilience.

Bros na how much you buy your battery.

My brother without been told, you will know those are fake panels.

How can 2700w produce less than 1kw instantaneously and you say it's not fake?

Don't you think you should have added your input rather than accusing me of what I failed to do?

Is this how you people accused Nigeria govt for failing to provide job for lazy youths?

the controller will control its output and it will not be damaged

Bgee77:
What happens if solar panels watts exceed the MPPT charge controller, where voltage and current are okay?

Okay

Go for 12v system, 24v is a waste of money if it can not power a submersible pump, u can get a 1.5kv 12v inverter, am using a 12v system wit one 220ah luminous battery and it powers my refrigerator of 150watt(inverter refrigerator) though I use it during the day 12pm to 4pm, it also power my LG washing machine of 620watt and blender of 600watt while I power my tv of 55watt and qasa fan of abt 30watt with all my indoor light during night I also use my TV and decoder during d day on weekend, if u know u will upgrade later buy 60amps mttp cc and bigger watt panel

Machiny:
am interested in this contribution because mine is still around 300watt. But my emphasis is on a freezer of 100w, tv of 45w, rechargeable fan of 45w, with phones. My questions are can an inverter power the freezer directly through solar? Can a 12v set work effectively as a 24v? Whts the benefit over the other? Can price tag required materials to achieve 160ah proposed on lifepo4.

thanks for this..which inverter can you recommend? Thinking of going lithium, since am on a low budget what size can matchup your 220ah battery? Heard there are inverters that can power appliance directly while also charging the battery.

all inverter can power yr appliances directly while charging u just have to oversized yr panel to accommodate yr day time load

big thanks

Am in search of a good 2.5/3/3.5kva 24v inverter.

I wanted to go with the growatt system , am ok the datasheets i saw but the previous statements here abt the mppt side switch on and off just discouraged me.

I would appreciate your response

Hybrid or Standalone?

TechGeek777:


Hybrid or Standalone?

do you have recommendations for any?

Also are their datasheets available...this will make me choose one over the other. Sometimes one might want to compensate a hybrid installation with a seperate controller..

Currently load consumption is 15kwh plus...appliances run for 10hrs

Crown Ricco Plus / Grovolt 3.5kva (Standalone) - No Load <= 35W, AC charger 20A-30A

Who gets 1.5kw 12v PowMr hybrid inverter for sale?

Currently doing a dry run.

How far does my battery discharge overnight?

Given that I have now disabled PHCN charging.

Can my solar panels recharge the batteries to float? If yes, in how many hours?

I am planning to transition the majority of my load (except AC, microwave, iron) to my alternative power supply by July 31, 2023.

You know 80% of Inverter user today do not put off their inverters and the scenarios described earlier are for cases of Inverter being turned off.

Also, the idle current is something that i will dispute but then i have inverter within reach to test with.

If you are an installer, nothing beats being able to diagnose and troubleshoot a problem remotely.

Good pm house

I bought a 2.5kva smarten inverter and 220ah Interlight Tubular battery and shipped it across to my state.

I thought that was the end but it won't on o. Den say I have to buy another battery to add it to make it 24v before it will start and account don red like this.

What is the temporary solution pls? Can I pair the 220ah tubular battery with 50/100ah dry cell battery for mean time?

Its either u get an extra battery same as the one u got or u buy a 12v inverter to use for the main time or buy a 24v lithium battery and sell off the tubular battery . The more economical option though is sell the battery and get a 24v lithium battery

Lithium is not cheap.
24v lithium of 100A is roughly 320k.
