What have I discovered about windsave inverters

• The WS seems to work well powered with a PMA.
• The brake is easily deactivated without touching the inverter board but if the relay is just bypassed then the contacts feeds still seem to be shorted out.
• To deactivate the brake pick up the other pins on the relay. Cut the track on the circuit board and feed the +ve and –ve from the existing pins to the other pair of relay pins. Use 1 contact for the +ve and the other pair for -ve
• The inverter will not go off initialisation if there is a DC applied to it. Even if the brake relay is closed.
• Error code err02 seems to be over temperature and will reset when the temp comes down.
• They go to code err02 if operated continually at more that 850w
• It is to misplace the lower of th two connections on the right of the inverter board. If it is misplaced by one pin down the display shows AC as an error.
• The connection of the ribbon cable to the display panel is very fragile but can be repaired if it does break.
• The WS inverters can be used in parallel but the input cables should be the same lengths.
• If operated with the cover removed for long they seem of overheat and go to err02. This is not so prevalent with the covers fitted.
• The fans run almost continually but don’t come on immediately and continue to run after the DC is disconnected – they must be temperature controlled.
• On standby they draw not less than 7W and often more.
• With the brake on they draw 14+W
• They deliver @800W with a DC input of @240V
• There seems to be a significant difference between the total generation meter and the readings on the Windsave which are higher!
• One of the inverters outputs more than the other for the same input voltage.
• One of the inverters has failed. Nothing lit up in the display, ac power relay not switching on.
• Both inverters have failed. Do not seem to be up to 800w 24/7.
