* PWM signifies direct connection to battery with diversion load control. All off grid MPPT
turbines can charge 12, 24 or 48 V battery bank except PLT40 which can only be used in 12
and 24 V systems.

5.3.6. PowerSpout LH
Common PowerSpout LH and LH Pro products
All LH and LH Pro products connect via MPPT controllers or grid-tied inverters. There are no
direct battery options available as propeller rpm is critical for best performance. Numbers
refer to maximum Voc. An LH150 for example has a maximum runaway voltage (Voc) of
150 VDC. It may be less, and is generally in the band 110-140 VDC .
 LH150 and LH150Pro – use with MPPT controller rated for up to 150 VDC charging
batteries. In a few cases with long cables, the MPPV could be slightly low for 48 V
batteries. Check with us if you plan to do this.
 LH250 and LH250Pro – use with MPPT controller rated for up to 250 VDC charging
batteries. Cable voltage will be higher for better efficiency.
 LH400 and LH400Pro – use with MPPT controller or grid connect inverter rated for up to
400 VDC. MPP cable voltage may be as low as 140 VDC in a few cases.
5.3.7. Special PowerSpout options
PowerSpout products can be tailored to meet specific requirements as required. MPPT
controllers, voltage regulators and grid connect inverter technology changes quickly.
PowerSpout turbines can be made to suit these new products.
5.4. Cable sizing
Some energy will be lost in the cable due to the heating effect of the current. This manifests
as a voltage loss in the cable, usually expressed as a % of the operating voltage. The
Advanced Calculator www.powerspout.com/calculators/ will either work out the minimum
cable size for you (given a target % loss), or the % loss for a given cable size. This tool
clearly demonstrates the effect that changing the cable % loss has on the cable size (and
