Dc-dc integrated mppt woes
I purchased a 280ah lithium battery, which so far is WONDERFUL. Also a 40a dc-dc charger with integrated mppt solar regulator. All worked well for about 3 weeks. After that the charger would still fully charge the battery on solar but then lock in. It did not recognise battery depletion & start accepting solar until the battery was unplugged & reconnected. So until I noticed via my shunt app the battery was not being charged at all. Communication of this to ecoworthy was frustrating at times. Several emails, lots of pictures & explaining. Had one offer of 40% off the price if I would keep the faulty charger. Not acceptable to me. I requested refund or replacement. They offered to replace. I’m still waiting 5 days later. I’m sure the first one arrived within two days! Well blow me down. New charger arrived today. Parcel a bit bashed but charger seems fine. It’s connect up & working now. I’ll have to wait to see if it’s solved the problem but fingers crossed.
