Best Dual Inverter combo for 7.5kW?

[SpitfireW'sale]

power one 10kw is g59 and nearest for purpose

I think that's 3-phase?

SMA 7000TL they are G59 i think, Steve at Wind and Sun has some in I think that he got for a job for me last year, I'm sure he'll be looking to get rid ;-)

Its a little on the low side at max DC 7200w but not far off

@PVNewbie, As I undertsand it the problem is limiting your output to the max allowed by the DNO, but not comprosing on production...

1) Try the EMMA EC - double win, 1) use as much energy as possible that uou generate, and 2) can limit the export. so you'd get a float top to your export without limiting power / energy production. used to be called EMMA GVS, Emma GVS | Worcester Renewables now called EMMA EC (need to update our page EC can be added as an option to any EMMA

2) SMA also have an export control device that powers down parts of the array to meet the DNO's limits, though not yet seen one of those installed in the UK POWER REDUCER BOX


Both the above are common practice in other countries, as usual , UK is a bit skow to catch on .....

Power One PVI 10.0 is a three phase inverter with two MPPTs.
