Hi all.

I don’t know much about fivestar brand and see they offer 20kw lithium batteries for under 40k compared to other known to me brands which are double the price.

just asking if anybody has anything they could say around the brand that could either re assure me or sway me away.

Appreciate the feedback

Morning all.

Anybody have any experience on this brand. Would greatly appreciate your opinions.

Thank you

why is nobody saying anything about five star brand lithium batteries 🤷 something im missing possibly

My neighbour had a 200ah Fivestar Battery paired with a Deye 5kw inverter and 10 x 550w panels installed. I being her “go-to-guy” on Solar, she hasn’t had any issues for at least 1-year now, with and the comms are working with Deye as well (LiBMS correct). Not sure which inverter you’d want to pair with this battery and your loads. Some inverters may not communicate may be the reason why no one is talking about them💁🏾

Also which particular model of Fivestar are you referring to? I’ve noticed there’s at least two different ones on the market. The one installed is on the pic. I've noticed they have more square ones.

Added pic.

I have had two Fivestar 400A lithium running in Parralell for about 6 months Using an Ecco 11kw inverter.

I have tried comms with the inverter, but definitively far beter by setting without comms and parrallel with network connections as per Data. The units have all the bells and whistles, except uses 6 led's for SOC. The LED's are actually pretty accurate. The Ecco Algorythms sucks. So only use that for gathering data.

I am still messing with settings but so far have streamlined and tweaked between 15 and 17kw out of each. Float Voltage 57V and low cut off to 47V. If cutoff is lower they enable undervoltage trip and need to be reset.

I am monitoring use on an hourly basis as i intend upgrading to the beter systems in 3 years time.

For the money, Aɓsolutely worth it.

I have numerous instalations with Fivetar batteries and synapse inverters, only problem I have had is one of the 15KW batteries BMS keeps going to fault and cuts power, One of my 15KW batteries is the old type with a Daren BMS, have upgraded it with a JK 16S 200A bms and it now can communicate with the inverter. Before just ran it on voltages and it has been running for +2 years. The one that cuts off the power is currently with the agents and they say there is nothing wrong with it. So looks like I will be swopping out the BMS with a JK bms as well. The newer Batteries have got Pacex BMS which communicates with Synapse/voltronic.

The new Fivestar batteries have touch screens which allow changing of the protocols.

The fist five star batteries had Daren BMS in them the next have pace BMS and communicate with LiB on the inverter, making sure you have the comms cable correctly wired.
