The kitchen is the most important part of the decoration. The cabinets are also the most critical furniture in the kitchen. How to avoid unnecessary waste in the decoration and choose a suitable cabinet for you? Here are five factors that affect the environmental protection of cabinets:
1, chemical pollution: In addition to formaldehyde, there may be harmful substances such as “benzene†and “ammonia†in the cabinet. In addition to the panel, there are cabinets and viscose that require related technologies to ensure the harmfulness. The substance does not exceed the standard.
2, special damage: materials, poor cabinet work may be in the details of the existence of long spikes and sharp corners, these untreated parts are very easy to make stone damage to the body, the direct treatment of food on the table, because the quality of the table Questions, debris, etc., are also harmful to health, there is noise and light pollution.

A solar inverter or PV inverter, is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Solar inverters may be classified into four broad types:
Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection.
Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
Battery backup inverters, are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.
Intelligent hybrid inverters, manage photovoltaic array, battery storage and utility grid, which are all coupled directly to the unit. These modern all-in-one systems are usually highly versatile and can be used for grid-tie, stand-alone or backup applications but their primary function is self-consumption with the use of storage.
