AEVA/AVASS Brighsun battery offer builds

Post by mark_hetho » Tue, 03 Jul 2018, 12:53

Hi,

Just thought I'd kick off a discussion about how people are planning to setup their battery packs, and share ideas on hardware etc.

We have an existing Grid tie hybrid inverter with solar and storage, and I'm thinking along the lines of adding another hybrid inverter and potentially more solar.

One of the things I noticed was that the 23kwh packs are going to potentially be difficult to completely charge in the sunlight hours - some hybrid inverters are limited in charge rate. The batteries are limited to 100A, so 4.8kw. Having a quick look around the models I've come across in with a charge/discharge in the >75A ballpark are the SolaX X1 Hybrid 5.0T, Fronius Symo Hybrid 5.0, Redback SH4600 and the Selectronic range. I'm leaning in the direction of a Batrium BMS and have noticed Batrium have documentation on connecting their Watchmon BMS to the Solax or Redback inverters.

The other path to explore are DC coupling options, but I haven't really investigated that at this stage.

I didn't think this was on the topic of EVs so I went straight to the lounge!

I am also now aware I can't delete a post that has been replied to :/

Happy for this thread to be deleted. Don't mind where the "official" thread ends up.

I'm beginning to thing we need a whole sub-forum devoted to solar and storage...
