Four 200 watt solar panels- pairs of two panels wired in series then those pairs wired parallel?
thank you
thank you
Voc; 21.8v
1000W / 28V charging = 35.7ASo now I'm thinking I should use five panels.
For parallel operation obviously you need an even number of panels. In parallel the voltage stays the same but the current adds. Depending on placement of panels and shading issues sometimes parallel operation is better. Also if constrained by a SCC's max voltage an array made up of parallel and series connected panels allows operation that an entirely series setup will not.I can fit five panels on the 6x12 cargo trailer conversion but settled on four b/c I thought they should be deployed in pairs (page 31 of Will's book Mobile Solar Power.)
So now I'm thinking I should use five panels.
Your thoughts on this and anything else.
