Any reviews of Knox PV 8000 infini hybrid inverter?

[AkbarGr8]

Hi all, selling my Pylontech UP 5000 48V 5KW battery. Less than 1 year old, excellent condition.

Asking 225K (negotiable).

Location: KHI.

[mgalaxy3]

Good luck on the sale!

Are you going battery less or going for a bigger bank?

[AkbarGr8]

Thank you. Bigger bank.

[mrdeejay]

Which battery are you going with now?

[AkbarGr8]

Pylontech. Newer series.

Does anyone know if/how net-metering contract can be cancelled?

Can anyone please share their experience with any of the following Hybrid inverters:

• Fox 10kW H3-AC3 Hybrid inverter with Fox (5.28kwh Lithium battery)
• Inverex 12kW Hybrid inverter with (Inverex 48V 100AH Lithium battery)

Does anyone know if/how net-metering contract can be cancelled?

what is validity of contract. If it is coming to an end soon, advise the service provider 3 months ahead of the date, for termination and to disconnect your green/white meter with conventional meter only.

[mgalaxy3]

Haven’t heard about Fox much.

Inverex is widely used and has good local support, based on Deye inverter and you cannot go wrong with it.

You don’t have to get the Inverex battery though it’s super overpriced.

Solax LD51 100AH is for 193k (ip40)
Solax LD53 100Ah is for 275k (ip65)
Dyness DL5.0C 100Ah is 248k (ip20)
Pylontech 100AH is 270k (ip20)

All work with inverex inverters BMS compatible. IMO cannot go wrong with any of these. Solax LD51 is performing well for me. Brand recognition wise Pylontech and dyness are well known too.

[mrdeejay]

Are there any stackable lithium batteries available in Pakistan? Like these ones: https://dyness.com/tower-pro-high-voltage-storage-battery-for-household-use

[mgalaxy3]

Asking for someone
What’s the best way to add a hybrid inverter+lithium batteries to on grid setup?

Does the normal household supply feed into the hybrid inverter, which then charges the lithium batteries from household supply?

And then at the end of the month the net units are generated in bill?

Or
Does hybrid inverter get connected to its own panels and own circuit or something?

Which is hassle free and safe?

[mgalaxy3]

I think most batteries are stackable (at least LD51 from Solax is) but will not resemble the look of the tower battery you linked.

[AkbarGr8]

Please get more details with regards to the ongrid inverter. Brand / kw / solar panel details / number of strings used.

Ideally if the ongrid inverter has 2 strings, 1 can be shifted to the hybrid inverter so that it can charge the batteries and partially support the house as well (can connect load which you'd like to power during an outage).

[AkbarGr8]

Personally a fan of Nitrox 10KW SP or Nitrox 8KW 3 phase (net metering compliant). Pylontech UF5000 series batteries OR Dyness 5.0C batteries.

[mgalaxy3]

Thanks! Will relay the info.

Btw Solax LD51 has completely changed my mind. It’s going great working flawlessly and comes at a very good price.

In the age of dropping lifepo4 prices, I’m starting to boycott batteries still available at anything over 200k for 5.12kwh 6000+ cycles. Gotta bring the dropping China pricing benefits to Pakistan.

[AkbarGr8]

I believe the solax battery is made / assembled in PK. Not sure of the BMS type but I believe it does work properly.

[mgalaxy3]

Yes and yes. Solax opened a plant in Pak and this LD51 is now also available in some other countries from what I’m seeing. Not sure if they are exporting them from Pakistan or directly sending from China. They already have good presence in the UK.

Working flawlessly with nitrox as well as Solax own inverters.

[mgalaxy3]

More on their factory/manufacturing plant that they opened in Pakistan (hate that they're calling it Li-Ion when it is LifePo4 ):

I'm expecting good service/support from them as Solax are localizing their products.

[AkbarGr8]

Hoped to catch a glimpse of their assembly facility but no luck there lol
