(1) filter electrolyte capacitance
When frequent-changing load causes increasing pulsant current and aging electrolyte
under high ambient temperature, the electrolyte capacitance may be damaged and
here should replace it.
5.3 Repair guarantee
(1) Within 18 months from purchasing date, if failure caused by inverter itself takes
place under normal conservation and usage, we will provide free repair service.
(2) We will take some upkeep if one of following situations takes place within
period of repair guarantee.
a. If did not use the inverter according to
《 service manual 》 strictly or did not use it
under ambient demanded in
《
service manual
》
, which cause failure.
b. Failure caused by applying the inverter to non-normal function;
c. Failure caused by self-repair, refit which is not already allowed;
d. Damage caused by bad keeping, falling down from high place or other extrinsic
factor after purchasing the inverter;
e. Failure caused by natural disaster or its reason such as unwonted voltage,
thunderbolt, water fog, fire, salt corroding, gas corroding, earthquake and storm etc.;
f. Make bold to tear up product logo (such as: nameplate etc.); Body serial number
don’t accord with that in repair guarantee card.
(3) We calculate service fee based on actual cost, which is subject to contract if any.
(4) You can contact the agent and also our company directly if you have questions.
After repair guarantee period, we shall also provide lifetime charged repair
service for our products.
5.4 Storage
The user must pay attention to following points for temporary storage and long-term
storage after purchasing the inverter:
(1) Avoid storing the inverter in high temperature, moist place and place of dust,
metal powder and assure good ventilation.
(2) Longtime storage will cause electrolyte capacitance of low quality, so must
assure that it’s electrified for one time within 2 years and electrification time is not
shorter than 5 hours and input voltage must be increased to rated value gradually by
voltage adjustor.
