Since new my Multiplus 1 48V - 5000 has a charge voltage error of 0.42 V ( low ) . Now this is normally not a problem , but I am considering paralleling another one and if that one is correct will I not have a problem with the sharing of charging load? Can this error be corrected / recalibrated
I note from your profile you have other kit too..
This can't be 'recalibrated', but you can use DVCC to source it elsewhere (BMV say) and share that same V across your whole system.
My own identical Multi was 0.3V out, so you're not alone. I now share V and Amps from a Smartshunt, and Temp from the Multi. It works well..
Great will try it out
tried it on my system and max charging current is only 42A on a 5000-100/ 70 Multiplus . Disabled all limiting on venus and set limit to 70 A on VeConfig. Bit annoying - Shall I specify a limit of 100 A or so ?
Not sure. There's a current limit in DVCC you can turn off..
But if you find having DVCC enabled is causing unwanted limiting, please try to nail it down. I see some strangeness with one of my generators, but always assumed it was the generator..
Voltage limit does not seem to do anything , current limit however works . The reason for the current limit previously kicking in was that now with SVS the true voltage was approaching the programmed absorbtion voltage. I now need to reprogram the charger voltage to reflect true voltage and not adjusted voltages ( by 0.4V ) programmed into Multi
