If you have a lifepo4 battery with a bms you should be able to charge directly from several panels wired in series and have the bms monitor the charging just the same as it would for any other charger. I would carefully monitor the voltage with a volt meter for at least the first couple of times though. I would check the voltage of each cell too.
