Hi,
I have searched for some help but can't really find the answer I need:
I have the following:
2 x 36 volt 10ah electric bikes
2 x chargers. Input - 240v ~ 1.8A max, Output 42v - 2.0A
The motorhome has:
2 x 85ah leisure batteries (new)
1 x 100w solar panel
1 x 1000w quasi sine wave inverter
My problem:
I tried charging both batteries together on the inverter and the battery low warning came on before both were fully charged but it was a bright but not sunny day. Overnight, as there had been little sun during the day, the batteries were still very low but everything worked fine during the day. As we were again off EHU for a few more days we decided to play safe and have a night on EHU and get fully recharged. All fine again but didn't risk recharging the batteries for the remainder of our trip on the inverter and managed to get the bike batteries recharged on mains at the site wardens caravan (the site had no EHUs for other motorhomes or caravans).
As a by the way, my solar set up keeps my motorhome going more or less indefinately when just using the normal stuff - satellite tv for maybe an hour or so a day, low consumption led lights, water pump, etc.
Should I have charged 1 bike battery at a time on the inverter during the day?
Is my set up sufficient to charge 1 or 2 bike batteries?
Does anyone else have similar who can share their experience?
Thanks in advance for any help.
