PowerTop V3 User Operation Manual
Q: Is the PowerTop battery replaceable?
Yes, battery can be replaced.
Q: How can I increase the charging speed?
For faster charging of your PowerTop, you can connect an external 20A maximum charger suitable for Gel batteries
following the instructions on page 5 of this manual.
Q: Can I remove the screws and open up the PowerTop?
No, the PowerTop is designed to be a self-contained unit, removing any screws voids the warranty of the unit.
Q: Should I use a regulated or unregulated solar panel with the PowerTop?
For unregulated solar panel connection through the red Anderson plug read page 6. For
regulated solar panel connection through the grey Anderson plug read page 8.
Q: If the vehicle voltage is not above 13.2 V can I charge from the vehicle?
Yes, you can. For the old dual you need to use the Grey Anderson plug instead of Blue Anderson plug with a DC-DC
charger such as CTEK D250S Dual. The car smart alternator will be connected to the “solar input” (not alternator
input) of the D250S Dual through a change-over relay and the output of D250S Dual is connected to the Grey
Anderson plug of the PowerTop. The relay will ensure the charging is stopped as soon as the vehicle ignition is turned
off so that the car battery does not go flat. The relay will also ensure any solar panel connected is charging the system
through the Dual’s MPPT and the charging current from the vehicle alternator gets switched through to the DC -DC
charger. The solar input of the Dual works as low as 12 volts (unlike all others which are 13.2 volts) which is the major
reason you need this setup with a smart alternator charging system. For the new D250SA
– You need no relay; simply
install as per the user manual. The Grey Anderson connector accepts the D250SA.
