Paired perfectly with my 100ah self heating renogy through hub

Great work on this, I managed to use it to pair to my 100ah lithium battery via the hub from my laptop. Great little starter kit to build a monitoring dashboard.

Awesome, that’s great news. I’m thinking of also buying that exact same battery. Would you recommend it so far?

Finally got it installed on the weekend, so far so good. I think the biggest negative for me was that it doesn't support series wiring (24v / 48v) so it doesn't feel super future-proof however there's not that much in the way of 48v gear out there at the moment. 100A max discharge is also a detractor, I run a 2000W inverter off of it but on a 100A fuse so if I go over 1200W then it'll shut off. It's a fun challenge to try and keep everything under 1200W - totally doable.

Bluetooth has been pretty stable so far. Haven't had a chance to test self-heating yet, it'll be winter here in a few months - will know then.

Well I’ve gotta ask. Where do you have it installed to? I’m looking for a battery to go in a teardrop trailer. My 200ah battery is a little too big.

We've got a bank of panels next to an outside caravan we're using as a guest room so it's a stationary setup. Bluetooth is still pretty stable. Inverter is a major parasitic drain though and unlike the rest of the Renogy gear you can't switch it off remotely.

The renogy solar charge controller we're using (https://au.renogy.com/rover-li-60-amp-mppt-solar-charge-controller/) has pretty good UI in the app. It seems to have memory, so it stores historical data about solar generation and usage which is really cool. Unfortunately it's super limited because:

1. The charge controller max output is 20a, so if you're using an inverter all of the usage stats are moot because you need to go direct from the battery. But if you're ok to peak at 20a then I would use the output of the charge controller to get all those stats.
2. Once the battery is full the charge controller stops generating power (has no where to put it) but that means your generation stats are a little bit meaningless because you don't know if the 1kw you generated that day was the peak of the system in those weather conditions or the battery was full by midday and stopped generating.

Still a pretty good system but I think their new 48v all in one gear might be better for off grid setups once all the 48v accessories catch up. https://www.renogy.com/48v-3500w-solar-inverter-charger/
