He doesn't want battery backup?

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?

Subject: Faulty PM-60 circuit board
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.
