Change low voltage perimeters

Ben

i have an inverter that's manufactured by PV Powered. I have been trying to get technical support and I've been told the company went bankrupt.  I would like to change the low A/C voltage perimeters.  They are factory set at 105.6. V.  I would like to change it to a lower setting, can anyone assist me?  Ben

Hi Ben, Welcome to the forum.

It looks like only PVPowered field techs have the capability of adjusting those settings. This is from page 8 of the manual.

Inverter Voltage and Frequency Limits

The inverter is factory calibrated to the voltage and frequency limits specified in Table 3-2. This voltage range can be adjusted by PV Powered field technicians under special circumstances.

Condition Factory Setting Adjustable Range (VAC) Models 2000, 2500, 2800, 3000, 3500, 4600, 4800, 5200 Adjustable Range (VAC) Models 1100 Maximum Trip Time(s) Voltage phase high 132.0 132.0 - 142.0 132.0 - 142.0 < 1 second Voltage phase low 105.6 95.6 - 105.6 95.6 - 105.6 < 2 seconds Voltage phase fast high 144.0 144.0 - 156.0 144.0 - 156.0 < 160ms Voltage phase fast low 60.0 < 60.0 < 60.0 < 160ms Voltage high line to line (240V inverters) 264.0 Voltage low line to line (240V inverters) 211.0 Voltage high line to line (208V inverters) 228.8 Voltage low line to line (208V inverters) 183.0 Line frequency low 59.3 Hz n/a < 160ms Line frequency high 60.5 Hz n/a < 160ms Table 3-2 Invert

You could make the same enquiry at Solar Panel Talk Forum. They have a larger grid tie community.
Good luck
