The Battery Thread (Solar / Inverter)

[wingnut771]

Hey all, if you'll had a choice, would you choose 2 x us3000c pylontech or 2 x hubble am2 5.5kw. Both around same price.

I would choose 2 x hubble am-2. 11kwh vs 7kwh, nevermind, 1 x hubble can output 5.5kw when 1 x pylontech can do 1.8kw.

How many times do people actually discharge batteries at a 1C rating, that means 5500 watts
Also the us3000c is around R18,000, @superskully , maybe you meant the new US5000C

I think it's called the UP5000 and pricing is around R24k. I see its also compatible with all the other pylontech batteries. This will be my next addition in 6 months time.

From the installation manual.

Sorry, I meant 3 pylontechs. It's the us3000c which gives 6000 cycles at 95% dod, better than the up5000. I can get 3 of them at 54k. Total 10.5 kw.
Hubble I can get 2 at 48k, total 11 kw.
Not so worried about the 1c as with 5 kw inverter.

 

[AchmatK]

The bigger the battery bank, the less relevant the C rating becomes. Your 5kw inverter will only be able to use them at 0.5C in any event.

I've got 4 us3000 batteries and would go with pylontech again if I had to do it all over.

Hi. Which place is that Hubble price from, if I may ask? I want to buy one at the end of the month. I have a 3kw inverter and want to wall mount so the Hubble AM-2 is ideal for me. Thanks

The hubble looks better on paper, but pylontech is known globally with good reviews.
Tough decision as this is a 20 year one.

Thanks. I emailed them two days ago to confirm pricing and availability, but no response yet.

He is very busy, it took a week to get back to me.

Yeah same here...

I don’t know why @wingnut771 is so hard up on Hubble , which is new and unproven.

Pylontech is a proven product worldwide.

 

[wingnut771]

I dont understand. They sold the inverter and the batteries together. I missed the fact that the battery is not supposed to be discharged below 50%(80% according to some resources online) but from the specification of the Inverter it will turn itself off after the battery voltage is below 10v.
This means the battery is getting damaged because of the inverter.
I was actually planning to buy new batteries but even if I do it's not going to last long because of this inverter.
So I have two questions:
1. Can i claim warranty on the battery? Its the royal battery from makro.
2. What's the easiest solution here investment wise ? 720watts for 2.5 hours is all I need. But something that can last for the next 5 years at least

Forgot to mention, when using that calculator, work out the power factor of the inverter by taking the wattage divide by the Va, eg: 720W divide 1200VA = 0.6 PF. Take your killawatt reading and multiply it by 1.6 and enter that as your load in the calculator.

EDIT: @joker08, sorry my maths was wrong. Take your killawatt reading and divide by 0.6PF. Other inverters have 0.8PF (Synapse 2400W/3000VA) or 0.9-1PF.
So if your killawatt load is 100W divide either 0.6, 0.8, 0.9 or 1 = 166W, 125W, 111W, or 100W respectively.

I have no problem with pylontech, it was on my wish list, but now that I'm aware of Hubble, I would prefer to support local is my main reason, second is 1C continuous draw, so less chance of overloading battery and messing up the warranty. People on a budget can start with 1 battery and not be compromised.

Hubble uses BYD cells which is a proven product worldwide. Just my personal preference, Pylontech is great too.

 

[Priapus]

I have 3 x Pylontech US3000's and would go Pylontech again. At the moment I don't have a need really for another battery. But if I do get another one, it will be Pylontech again. But the newer one.

again it comes down to the individuals application.

your C rating point can only go so far, and as @signates pointed out, it becomes irrelevant at some point.

batteries are a long term purchase, so passing judgement on new brands without results so early on is a little irresponsible IMO.

But making a 20 year purchase on an unproven brand is responsible? (Playing devil's advocate here. I'm probably going to buy a Hubble or Bull pretty soon, but I realise I'm buying an unproven product)

I hear you, I'm just saying what I would do when I pull the pin. Just my opinion, use it don't use it.

Hi all,

Planning on sorting out the load shedding and were quoted on this inverter and battery, what is your opinion on these products?

Synapse 5.0+ (Hybrid Inverter 5kW 48V DC, 80A MPPT) - R11,591

Hubble X100-48 (BATTERY 48V LITHIUM (LiFeP04) 4.8KWH) - R29,302

Hubble X100-48 (BATTERY 48V LITHIUM (LiFeP04) 4.8KWH) - R29,302

That's a pretty big battery if you're only wanting to cover a 2 hour load shedding shift. Depending of course on what needs to be powered during LS.

Never heard of the inverter so can't comment on that.
