[RE-wrenches] Buried Conductors

I am working with a customer who is doing a complete remodel, and upgrading to PV and Smart Energy Storage. The house was broken down to floor joists, open studded walls and open roof rafters. The client wanted a 8 kW/16 kWh Smart Energy Storage system and a 10 kW-ac PV system. The Main

Re: [RE-wrenches] Add-On to DGT, string inverter, w/Different Modules on 2nd string

HI Ash, You don’t give a lot of data to the system, tilt, orientation, probably its 12 in series ( probably?), location, or room available for added modules, how difficult to add new wires or are the wires off the roof large enough to handle another string of modules, does the inverter have

Re: [RE-wrenches] Add-On to DGT, string inverter, w/Different Modules on 2nd string

Hi Ash, Long time no see. I would consider replacing the entire array. The new high wattage, low cost modules would allow you to match the existing inverter's voltage with new modules at a surprisingly reasonable price. The customer may be amazed at how cheap they are, especially since he

Re: [RE-wrenches] Building strings of modules with variable voltages?

Solmetric has some good screen shots of what happens when you combine these modules. My students just did a lab of combining modules (210W and 175W) in series and parallel and testing the PVA 600. In series V add and current drags way down to the lowest I value in the series string. The IV

Re: [RE-wrenches] Building strings of modules with variable voltages?

I hate to say in public but l have paired up modules stacked simular to what you want to do, what l have seen is IMP slightly less but still way better then seperate so give it a try. I have done it for the same reason you are looking at. Jerry On Jun 22, 2016 7:37 AM, "Daniel Tittmann"

Re: [RE-wrenches] Building strings of modules with variable voltages?

Dan; rough-and-tumble world indeed here off the grid! My understanding is that Voc will still be additive, minus degradation over the years, but that the larger Pmax modules will be current limited for Imp by the smaller ones. So your 245w modules could only do 100w in the scenario you give. My
