Dyness 5.12 vs Weko 5.3

GTE

Hi all,

I am tossing around two quotes for a panel and battery installation and I am trying to get to grips with brands as I enter the solar knowledge base. What I know from EVs is to watch out for the usable kWh from any battery.

I have two companies which have provided the lowest cost quotes.

Company A offer:

• 5.3 kWh Weco battery (W5K3XPLV)
• Datasheet says it has an "up to 100%" depth of discharge.
• Cost is 1469 euro
• Plus 10001 euro for 18 Jinko 435 watt panels and Solis inverter (JKM435N-54HL4R-B and S6-GR1P5K)
• 11470 grand total (deposit is 4588)

Company B offer:

• 5.12kWh Dyness battery (no model number given)
• Some Googling shows a data sheet for a similar battery which has a 90% depth of discharge or 4.6kWh usable.
• Cost is 1250 euro.
• Plus 9450 euro for 18 Jinko 430 watt panels and Hypontech inverter (no model numbers given)
• 10700 grand total (deposit is 2000)

Company B has a few boardsies approval based on the recommended installer list. Company A is not on the list, but has a very impressive quote website, and has quite a few informative blogs, as well as solid Google reviews.

Am I over thinking the battery side? Some posts here recommended the Weco over the Dyness. Is 219 euro worth 0.8kWh extra? Perhaps, but Company A are charging a wee bit more for the panels.

Many thanks for the advice. I am looking for the best value and return.

I have the Weco and it's been very good but have nothing really to judge against. Even though it has 100% depth of charge the Solis inverter will only allow it to go to 5% fyi.

Company A are selling you a string inverter with a DC battery so get them to confirm their equipment.

Thank you for the heads up. I called them and they confirmed there is a hybrid inverter (S5-EH1P5K-L) in the quote for the panels and battery. It turns out it was my own silly typo!
