Wiring & Setup:
MULTI-BATTERY SETUPS
The SFK-300HP offers various multi-battery setups, these allow you to increase your total available am-
perage as well as voltage. The flexibility of this allows batteries to be used in 12v, 24v, 36v, as well as 48v
setups. We will detail the options below.
NOTE:
for many parallel setups we will be recommending the use of a common DC bus bar with equal
wire lengths to ensure proper load splitting. The Sun Fun Kits DC Bus Bar works great for most parallel
setups: https://www.sunfunkits.com/product/35/heavy-duty-bus-bars-250a-600v . We always recom-
mend you consult an electrician before proceeding to ensure your loads are adequately spread among
your batteries.
The SFK-300HP should only be used with batteries of the same type. You should not mix and match
SFK-260, SFK-260HP, SFK-275HP, or SFK-275EX batteries or batteries of other brands in the same bank.
Doing so may overload or cause unequal loads in your bank. Regardless of which setup you decide to use,
the total number of batteries in a bank should not exceed 4/bank. If you need more than 4 batteries, you
should consider making another bank and then connecting them with appropriate load balancers.
