Took a couple of days, but the owner of NovaCraft passed on the question of the RS232 port on the Esener 16kWh battery
They then sent him a photo of the ports. Standard Pace BMS, including the RS232 port.
Also noticed a plastic pouch with Bluetooth and WiFi QR code attached. That would be a bonus too.

I asked him to communicate with Esener and request that they update their concise spec sheet accordingly if indeed this is the Esener 16kWh

Thanks for this. Ironically, Sinogy are the company that installed my Solar solution 2 years ago - they are indeed legit.
I wouldn't say they were perfect, but a solid 8/10 in terms of their service offering and pricing. Definitely no risk in buying from them.

I don't know if the standard Series Stage 1 is any good, most installers I've spoken to say good things, but I honestly don't know. Because I've had Shoto's installed and the installer swears by them (I have no complaints, but it's only been 3 months), when another sparkie came on site to do the COC he called them the fire batteries (which refers to a few isolated incidents/problem that were fixed years ago on old models). People tend to have confirmation bias.
Paying a bit more for the Pro would ordinarily pique my interest, because one would assume improvements and lessons learnt would be applied to the 2nd gen, but apparently it is a completely different unit, a Deye battery in Volta packaging - in theory good, but in reality, is it worth paying more for? The 90% DOD was noticed vs 80%, but I take those stats with a pinch of salt anyway... because 6000 cycles is 10yrs away...
It's hard to trust the stats from brochures. I'm too far down the rabbit hole to switch brand choices at this stage, I'm limited to these 2 options unfortunately.

Svolt might be cheaper, but I gotta say, this Volta looks pretty good, and performance so far has met expectations.

Fair question... I just don't want to mess the installer/supplier around... we agreed on a deal which I think is reasonable and I don't want to change to a battery they might not be as experienced with to save a few bucks. (The 10yr Deye/Volta warranty bundle is a slight advantage)
But yes, I've stuck to the S series to save just over 2 grand because I have a budget and paying cash...

Good afternoon,
Been offered the Volta S Series Stage 1 (5.12kwhr, 100ah) battery and the Volta Pro Stage 1 (5.32kwhr, 104ah) batteries for a new install... is it worth the premium (10% price difference) to get the Pro?
Anyone with experience with them?
I can see basic differences on their website, but no real world opinions/experience that helps me decide: https://voltaenergy.co.za/volta-pro/
 

What's the consensus on mixing battery brands/models on an existing installation?

Svolt might be cheaper, but I gotta say, this Volta looks pretty good, and performance so far has met expectations.

I did not realise Volta had a pro battery - curious to hear what the difference is between them.
 
I see DoD on the S series is 80% and Pro series is 90%, I assume the pro series use better quality cells.
Both have a 10 year warranty so not sure how much of a difference one would feel between these 2 batteries.
 
Pro says powered by Deye, so likely just a rebranded battery as well...
 
I personally still love my Svolt batteries, value for money is exceptional and makes it hard to justify other batteries.
Volta had some issues with their batteries not charging properly although I believe this was resolved with a BMS firmware update which at least shows that they are providing some support and fixing issues where necessary.

That would be the reason. If the output exceeds 50A, it will cut out.
