QUESTIONS & ANSWERS
Ask a Question-
Can I maintain 3 batteries on my boat at once ? If so how I hook up wires to batteries ? Thank You
Yes, you can maintain 3 × 12V batteries with the BC-20W-PRO, but only if the batteries are connected in parallel. While it will work, the BC-20W-PRO is still a relatively low-power maintainer. For your setup, we would actually recommend a higher wattage model such as our 30W / 50W version. These will provide much better charging performance and more reliable maintenance for camper batteries, especially if you are using three batteries in parallel.

Can put two Suner chargers in parallel (e.g. a 10 watt and a 20 watt)? ?
Yes, you can connect them in parallel. Each Suner BC-20W PRO (or other Suner PRO models) has its own built-in MPPT controller, so you can safely connect multiple panels directly to the same battery. They will manage the charging independently.

The cable coming from the solar panel is 3m-9.8ft, and 3-pcs cable adapters are 0.5m-1.6ft. If you would like to extend distance, you may consider our 16FT extension cable.
