Ive been looking at buying a 48v dc generator from Könner and Söhnen. https://shop.koenner-soehnen.com/en-pt/products/generator-ks-48v-dc In the spec sheet it says it charges at 70 amps which seems very high. My batteries are Pylontech 2x US2000 and 1x US5000. Am I going to damage the batteries...

New user, first post so bear wit me please... I have a strange problem. I recently installed 4x 460w panels to my off grid set up and everything has been going well. Today I check on my invertor how much power is going into the batteries (pylontech) and its under 100w in full sun! 186 volts...
