Sunny Boy SB-700
The Sunny Boy SB-700 is the smallest Sunny Boy solar inverter available (costing around £800 in the UK). The SB-700 accepts three different DC voltage inputs 250, 200, and 150 VDC (corresponding to 6, 8, and 10 PV solar modules respectively) with a maximum input current of 7 Amps. At 250 VDC, the SB-700 has a maximum AC power output of 700 Watts, at lower input voltages this falls.
The SB-700 is built in an IP65 rated waterproof and dustproof stainless steel casing making it suitable for outdoor installation.
The SB-700 can be simply connected to any location of the house mains electricity supply (for example in the garage or attic) – it is not necessary to have it connected directly to the house electricity distribution point. Therefore the cost of installation is relatively cheap.
