At higher volts..smaller current flows tru the cable...and vice versa....so sending at higher volts enables you use thinner wire..

Same principle why nepa transmits at high tension/voltage, we have 33,000volts, and higher for the national grid.this way immense amount of power is transmitted at negligible losses at extremely high voltages, which is now gradually stepped down at
or close to consumption areas.
Those giant pylons carry 132,000volts if not higher

Morning star 60amps pwm cc cost 198 dollars, same morning star 60amps mppt cost 600usd.
The Pwm operates at about 60v max.
The Mppt operates at 150v max.
The extra 400usd in cost is basically cos of this flexibilty in max input viltage grin

For solar calculations, using 3% loss and lower is a preffered optimal design factor than 5%
I appreciate thanks

Please what is the meaning of the Half-Cut stated on the panel.
Just an imitation of the Canadian solar panel.

Hello Gentlemen,

I don't know the right forum to ask this question, so i'll just ask here.

My apartment has this issue where literally all the appliances have small current on the bodies, especially the ones made with metal.

They zap you with small electricity when you touch them.

I've been told its because the building isn't earthed.


Please is there something i can do to help the situation, other than doing the earthing rod stuff. its a rented place

It's a split-cell technology methodology.... Saw that first on Canadian Solar. Kind of makes the panel more efficient.
Flames decided to adopt that too.. That's good

Former link


latter link



The first one has the features that I want. The latter is too complex for the application I want when compared to the former. I can only hope it can survive an air-conditioner constantly plugged in. Chinese and their fake specification are like 5&6. I see the 15A rating, but can it really survive that current is another story. This one you are using the alternate, have the bot bandit struck again? grin grin

Thank you very much for this, I'm definitely checking out the first one.

I assumed that since it is to be used for some remote application, having a SIM card integrated one for remote manual control won't be a bad idea.

You should at least be able to get 10A out of it, if the 15A is an over-declaration.

The main is still active but I deliberately used the alternate in case the bot strikes again, then I still get to keep the main. Apparently, the bot wasn't at home grin

• Is it on load (in use) while charging?

• Is the inverter those types that prioritize solar charging over grid charging or vice versa? Also some integrated in writers like that will not charge batteries if the voltage from the grid is low (like the low current NEPA is fond of)

• Also you may want to get a meter to measure the current flowing thru the wires from the inverter to the battery, at least to be sure that current being fed into batteries is adequate to bring it to float as you expect.

It is on the load while charging.
The inverter only has a setting for current adjustment and battery type selector. No display but it has led to show different performance inverter on, fast charging, and float charging etc
The voltage is high enough and the charging indicator is on but not going to full charge or float charge state. Thank you.

Normally you require 5 hours to fully charge 24v 200AH at 40A so it seem like a normal behaviour since you said you have load concurrently. It then depends on how much load you have concurrently

Due to the location layout and sort of sensitive items on location, user wouldn't want that sort of control. grin

Re: Solar Energy, A Complement To FTA by Israelicc: 3:50pm On Jun 25, 2020
Good day Sir,

Your observation is a classic example of a poorly earthed house. You may have to engage an experienced Electrical Engineer to troubleshoot your earthing system to be sure it exists as a good earthed house should pass all stray current to ground thereby avoiding electric shocks or shock sensations. Otherwise, you might also want to be sure that your LIVE wires are well insulated. It might just be that there is an insulation breakdown that need to be resolved.

I'm a little bit confused... I don't remember load affecting how effective an inverter charges a battery bank during Standby Mode...

When an inverter is charging battery bank through Mains supply, the Inverter usually operates in "Standby Mode". In this mode, the Inverter has an internal bypass that it uses to directly supply the loads connected to it, at the same voltage as the Mains supply. At the same time, the Inverter draws an independent power to charge the batteries.
The loads connected to the Inverter during charging from Mains Supply do NOT affect the battery charging.

Hi Ojtech,

First, you missed out quite some details.. You didn't specify if it's hybrid inverter or standalone.
I also want to assume that the battery bank is a combination of 12V 200Ah batteries connected in series.

You also didn't specify if the Inverter was actually outputting the 40A during the observation... Might be possible it's not. And also the quality of the Mains voltage

However, though it's new, how long it would take depends on the state of the battery.
I bought 8 set of Quanta Batteries last 2weeks for an installation. I put all through an independent pre-charge, which I normally do before installation. Each of them took between 8-10hrs to go from boost charge (@250-260W) to Float Charge (@30-35W). And yes, I monitor each using a Socket-plug wattmeter. Few of them were September 2019, while others were October. Been sitting in warehouse for quite a time, and I believe that's why they took that long to go through the charge stages... Otherwise, it usually take 3-5hrs

So, there are factors that could make it take that long. You could provide any other detail that might help

Lastly, I want to believe that those batteries are AGM or they are actually designed to handle such amount of charging current. 40A on a 200Ah Battery bank is quite big.... That is, if it's charging through Mains supply irrespective of whether there are powered loads or not

Cheers

Usually AE was a go to option but with China orders seriously troubled due to covid-19, I was hoping someone here will have them on offer.

Am I in luck?

I think you misunderstood me, my understanding was that he was generating 40A and it is from that he was charging and serving his load. There is no way all the 40A will be getting to the battery, secondly since it's lead acid, there will be significant charge current loss as well
