I have a ac500 connected with 4 b300 batteries and I have noticed that the ac charger fluctuates allot. It has gone from 1.2 kw to 329w to 846w to 259w. Is it normal for the constant fluctuation?
Since I’m off grid location I have never had problems keeping my system charged. I run a 25kw diesel generator that I run every night from 5pm to 11 pm which usually topped off the batteries. But I’m noticing that I’m currently at 53% and it’s 8:52 pm.
I would say no its not normal for the charge to fluctuate that much. I wonder if your generator is putting out stable power or if the voltage is swinging around or something else is wrong.
I believe you need to charge through a generator, preferable an inverter type, with a sine wave that is comparable to your ac500. Also, the manual states you might need to call them for a specific code if using a generator.
Hi @Castilloj73, We believe that the power fluctuations from generator charging are indeed quite significant. Could you please inform us of the specific model of the 25kw diesel generator?
We can push the latest generator firmware to you. Please provide us with the SN code of your AC500 and its current firmware version.
We extend our gratitude to @doecliff and @LukeWarm for their concern and solutions regarding this matter, which are very helpful.
