Frequ ent ly Asked Ques tions

1) Why do esn ’t the electric e qui pment work normall y after it is conn ect ed to the system?

Pleas e che ck the left energ y of ba tteries for the r eas on that

the equ ipm ent cannot work s moo thly if the energ y is no t enough. But if th e ene rgy is enough, ma ke su re whether the wi rin g betwe en ba tteries and inv ert er is correct.

2) Why ca nno t the batteries b e cha rged? Check w het her the blades ar e tur ning or not, beca use t he

gener ato r has no output at to o hig h or too low wind spe ed. B ut if the bla des a re running norm all y, ple ase d isconnect the c abl es of batte rie s and inverter at f irs t, then check the o utp ut of the gener ato r with a voltage me ter. I f the output is in ge ar, pl ease exami ne th e batteries are o k or no t, if the output is z ero , please check t he ca ble of the genera tor.

3) Why ca nno t the blades turn a t a nor mal wind speed or turn slowl y?

If the ou tpu t wire of the gener ato r is connected sh ort -circuit,

the bla des d on't work, plea se di sconnect the ca ble s of batteries and inv ert er, and then check t he ge nerator's cab le.

4) Whether can the using time of electro-equipment be prolonged through enhancing the capacity of the batteries?

If the su gge sted batterie s cap acity is added, i t wil l cause the

batte rie s to be a situation o f lac king energy in a lo ng ti me, which will in flu ence the life-s pan o f batteries and l ead w aste.

5 The generator cannot automatically follow the wind direction.

Pleas e che ck whether it is se t und er【Auto】state on

contr oll er panel. It will n ot fo llow the wind dir ect ion automatic all y under【M anu al】state. If it can n ot fo llow the wind dir ect ion

under【A uto】s tate, it is usual ly ca used by low wind sp eed . It

can onl y fol low wind speed au tom atically afte r the w ind speed highe r tha n start-up wind s pee d lasting for 10 mi nut es.

Check t he ba ttery voltage i nsi de the system. If i t is lo wer than

22.5V, the turbine ca n not y aw automatically.

6) Does the H- series wind turbines ha ve lightning protection?

Yes, the H-s eri es w ind tur bines h ave lightning protecti on. The H-ser ies wind turb ine s can handle 6000 Volts as re quired by relat ed regulat ions an d standard s. If you liv e in a lig htn ing pro ne area Hopef ul Wi nd Energ y rec omm ends an ad ditional lightning arres tor a t the base of the tow er.

7) What s hou ld I do if I'm expect ing a s evere storm?

The H-s eri es wind turbine s is de signed for very h igh w inds, but it is a lwa ys a good idea to shu t H-s eries wind turb ine s down if there i s goi ng to be a severe sto rm to p rotect agains t any f lying debri s.

8) How do I s hut d own H-series wi nd tu rbines?

To turn off the power switch of controller of H-series wind turbines.

9) What should I do if ice forms on blades of H-series wind turbines?

To avoid th e pos sibility of inj ury f rom ice breakin g loo se from the bla des a nd injuring any one , H-series wind t urb ines should be turn ed OF F if ice accumula tes o n the blades.
