Bimble Solar are the best people to buy solar kit from.
I had a few questions about what I needed and how to set up my system and they were very quick at replying and providing very helpful advice. I'd use them again and highly recommend them to others.
For 12V Solar System: 520W solar panel (150V for max input voltage)
For 24V Solar System: 1040W solar panel (150V for max input voltage)
No Fan for silent operation, great for vans, boats or any live in spaces
New updated model with better communications and ability to fully program charge voltages via Optional PC cable or Optional MT50 Meter
**Although you can program set points that are appropriate for Lithium batteries, Epever do not officially support charging Lithium with these controllers**
The BN tracer models have a current limiting function, you can connect twice the rated power to the controller so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer. The output will be limited to the max listed above.
The Tracer BN is identical to the OutBack FLEXmax Micro Series, they are made in the same factory, showing outback's faith in this MPPT manufacturer.
New Tracer series is EPsolar’s second generation of MPPT controller. Compared with CLASSIC Tracer series, it has extensive communication ability. And the die-cast aluminum design ensures excellent heat dispersion.
Compared to conventional PWM controller, MPPT technology increases the charge efficiency up to 30% and potentially decrease the power of solar array needed.
