Wrenches,
After telling my customer to upgrade to an MPPT charge controller (thanks
Ray Walters and John Blittersdorf), he decided to really optimize his PV
array and retire his Trace SW4048 inverter. He has 48 Siemens SP75 modules
(67.5 W DC PTC) that are ground mounted in full sun and easy to re-wire.
With so many new batteryless grid-tie inverters on the market, this is a
good time to ask this sage group with over 3,000 combined years of
experience what inverter do you prefer?

Wrenches,
My customer has a circa 2001 Pulse PC250 with a faulty PM-60 circuit
board TC-750, REV D2 (the microprocessor U1 has v2.5 and v1.01 written
on a label on it). Does anyone repair or have replacements for PC250
PM-60 circuit boards? If not, what do you recommend? Thank you in advance
for your help.
Joel Davidson
