Using as a PV dump can you supply with lower rated Immersion heaters to 2x 1kw or 1 x 2kw

Considering using as a PV dump can lower rated Immersion heaters to 2x 1kw or 1 x 2kw to mop up surplus electricity generated 2x3kw would cause me to be importing from grid as generating systems max is 3.5 ~ 4kw

Confused regarding size of the immersion heater thread your manual quotes a nonstandard 1 3/4" dia rather than the std 2 1/4" BSP please clarify do you use a reducer ? which can be removed to give access to standard thread? Please confirm low wattage e.g. 1kw & 2kw 2 1/4 BSP Immersion heaters can be used Many thanks
