Hi folks,
I have a spare 200W solar panel and DC bilge pump. My intention is to pair them directly (without battery) to aerate my fish pond for about 3 hours daily at around noon time. I would like to get some advices/suggestions on equipment matching and possible ways to improve this setup for better stability and efficiency.
DC bilge pump - Seaflo 3700gph 12v, rated 14amp.
Solar panel
Power output; 200 watts
Output voltage; 36.1 volts
Peak current; 4.98 amps
Open circuit voltage; 44.0 volts
Short-circuit current; 5.45 amps
I'm aware that output current from PV is much lower than the pump's requirement. I'm perfectly ok if the pump is not running at 100% capacity during the runtime (50%-70% are good enough for me). So my questions:
1) Will the pump run when current is lower than 14amp (eg: 4.5amp). If i swap to use 200W 12v 10amp panel, will the pump run, or the pump will run only when current is higher than rated 14amp?
2) Considering the low current from PV, I'm thinking to get a linear current booster (i.e. Solar Converters 12/24-15). Is this LCB a good fit to my setup?
With thanks,
Alan
