The measurements should be acceptable for your model's nominal
voltage:
850 VA to 1.4 kVA models: +12 Vdc (nominal). If you measure less
than 11.5V, check for wiring errors.
1.8 to 7 kVA models: +48 Vdc (nominal). If the batteries are
well-charged, the measurement may be as high as 51–53V. If you
measure less than 42V, check for wiring errors.
