At 6000 watts, 48 volts will work but you are near the top of 48 volt power range. That is the key is maximum Power, and the current required to push it at a specified voltage. At 48 volts with 6000 watt load you are talking about 125 amps of current and a minimum size FLA battery of 900 AH. So you are already locked into 2400 pound $8000 battery that will only give you 4 hours run time. That battery will need replace din a few short years.
Sammy do you understand what you are asking for? 6000 watts x 8 hours = 48 Kwh. At 50% DOD, a line you do not want to cross with Pb you are talking about a 96 Kwh battery. Do the math on that. A Pb battery weight 60 lbs per Kwh and cost $200 to $250 per Kwh. 3 years replace. Double what I quoted above. You are talking about a 5000 pound $20K battery every few years.
For a Commercial System using LFP, you want Top Balance because it is made for consumers and morons. It takes an expert to use a BB LFP. Pretty much takes the same equipment either way.
As for CALB my friend you are gambling. Yes I know there are claims they will do 2000 cycles to 80% DOD. Those claims have been there since Thundersky began manufacturing. They went bankrupt because no battery they made ever seen 500 cycles. Here we are 9 years later, and on the 4th revision. None have ever seen more than 500 cycles yet. You would be betting the Farm the latest revision will do what they claim. Do you really want to trust a bunch of Red Chi-Coms who have a terrible track record and known to be liars? Be careful with Chi-Coms. None have a proven track record. CALB, Sinopoly/Winston all are regurgitated Thundersky batteries.
Here in the USA CALBS are used by DIY EV builders. None have ever been able to file a Warranty Claim. Be careful. With LFP you can use a smaller AH battery. Run them between 10 and 90% DOD. Never fully charge them, they will last twice as long if you stay between 10/90. To replace a Pb with LFP for every 100 AH of Pb takes about 70 AH of LFP to replace it. Yes smaller and lighter, but more expensive.
Keep this thought in mind. You can get a top of the line Pb battery for around $220 Kwh. Assuming professional care an dTLC you will have a 7-year battery with full warranty from proven technology from reputable companies like Rolls, Crown, and Exide to name a few. A Chi-Com LFP will run you $450 to $500 Kwh and one can only guess how long they might last. Its a gamble. So be careful, your reputation is on the line. If done in the USA, and the batteries fail prematurely, the replacement cost comes out of your pocket. You would be held accountable. Chi-Coms don't give a damn if it bankrupts you, they are untouchable.
Good Luck to you.
