Parts of a Eco Worthy kit
6 String PV Combiner Box
Number of Max Connection PV Array: 6
Max Input Current of Single PV Array: 10A
Total Input Current of PV Array: 60A
Max Input Voltage of Single PV Array: 250V
Max Output Voltage: 250V
Solar Panels
Rated Power: 195W
Open Circuit Voltage (Voc): 21.6V
Short Circuit Current (Isc): 10.83A
Working Current (Iop): 9.02A
The kit is set up to put 2 panels in series (max 6 strings). That I assume is because the PWM CC that came with the kit is rated for 50v max input.
the question is: Can I put more panels in series to up the PV voltage?
The stats for the combiner box state: max input voltage of a single PV array is 250v - the way they word things I'm assuming array=string (Number of Max Connection PV Array: 6)
Upping string voltages would allow me to upgrade the PWM CC to MPPT.
additional:
I see I'm limited to 10a for any string I add and that leads to another question
Can a higher wattage panel rated at 10 amps be set up in series and added to the combiner box if the voltage is different that the other strings.
I've been pleased with my kit system, it got me up and running without any real knowledge. Originally the system was meant to provide power to my Maple Sugar shed for lights and an induction cook top for finishing off small batches of sap and occasional power tool use. What got me was I was making power or the potential and not using it on a regular basis. Solar panels sitting in the sun and not doing anything irked me.
So I tweaked the kit by adding a Moes ATS (compliments to Will for reviewing it). The system now runs my Aquariums but soon runs out of steam when the sun goes down (switches to grid when my Gel batteries (2s for 24v) drops to 24.4v. So now I've got a bug up my posterior to upgrade the system and battery bank to prolong the switch back to grid power and the extra capability would certainly help during a power outage.
