HI All,
i have been following many posts over the last couple of months and am wanting to build my own, i have already started collecting and processing battiers wiht no problem.
however i am a little unsure which inverter charger i want to use or a separate inverter and charger.
My requirements for my system are:
- Charger battierrs of eco7
- charger of excess solar
- be able to remove incase i move out
- reduce the amount of daytime energy used
- prefrably not high voltage dc
- not to expensive.
i have looked at the following options with the following pro's and con's
Sofar ME 3000sp
Cost: 700
Pros:
can limit output pwoer and take into account access solar power all in one box
3.3kw
48v
can act as backup
cons:
the battery options need rs485 comicnations, would need to either reverse engineer the rs485 protocol (or find the documentation for it)
or use the lead acid option and just set the parameters best i can.
GTIL 2000W with limter
300 for invter + xx for charger and controllers as need
Pros:
Cheap
limits power
cons:
need a separate charger which cannot find easily of the shelf.
would need separate backup power system.
Solar MMP MPI
pro, can limit power
cons:
expeinve and very little information on this feature
Solax
some great products but none 48 v
Has anyone got any suggestions of other inviters /chrages to look at?
Many thanks
Tom
