I have bought components which are not yet installed in a campervan conversion:
110ah leisure battery (wet bog standard):https://www.tayna.co.uk/leisure-batteries/enduroline/exv110/
380W JA Solar panel
Victron Smart Solar 100/30
Victron Orion tr Smart 12/12-30
I'm concerned about overcharging my leisure battery during the bulk phase of charging. Both the smart solar and orion will be connected to the battery in parallel. When driving on a hot day, I could be bulk charging the battery with 60a. I have no battery specs, so I gather general advice is to charge at a max of 0.2C or 20A. I see I can limit the output of the mppt, but the Orion will not limit current during the bulk phase. I gather the battery will utilise available current, especially when depleted.
I'm uncertain whether to buy the 18a Orion instead of the 30a. Even then, whether I need to switch between the mppt/ Orion so only one feeds the battery at a given time.
Or potentially whether the mppt could accept the Orion output and the solar as dual inputs, then I could limit the mppt output to 20a.
I realise opinions vary on the 'right' bulk charge rate for batteries, I just don't want to overheat the battery so I'd like to aim for approx 0.2c /20A.
