I recently had 920 Ah of 12v LFP batteries professionally installed on our sailboat. The installation used 2 Orion XS dc-dc chargers connected to the engine battery. Last night we ran the generator to charge the batteries through the 5kVa, 120v Quattro. We were also running the air conditioner. Batteries charged from 60 to 75% SOC with current about 150A when the Quattro charger shut down. We then shut everything down. Left it overnight hoping a breaker, if any, in the Quattro would reset. The next morning the charger will not turn on. Must use engine to charge the batteries. Any suggestions for diagnosing and fixing this problem are welcome.
