Finallyfor people working with ISO standards, the new ISO 20000:2018 is easier to understand, and also is easier to integrate with other ISO standards. Furthermore, you can decide to work with the PDCA, or not, but anyway, you can have a reduced number of documents for the same thing: managing your services.
For sure, the new ISO 20000 is not a unique option for the management of services, but it can give you useful tools in the form of processes to improve the quality of your services, obtaining the best customer satisfaction.
ISO/IEC 20000 is the international standard for IT service management. It was developed in 2005 by ISO/IEC JTC1/SC7 and revised in 2011 and 2018.[1] It was originally based on the earlier BS 15000 that was developed by BSI Group.[2]
ISO/IEC 20000, like its BS 15000 predecessor, was originally developed to reflect best practice guidance contained within the ITIL framework,[citation needed] although it equally supports other IT service management frameworks and approaches including Microsoft Operations Framework and components of ISACA's COBIT framework. The differentiation between ISO/IEC 20000 and BS 15000 has been addressed by Jenny Dugmore.[3][4]
Formally: ISO/IEC 20000-1:2018 ('part 1') specifies requirements for "establishing, implementing, maintaining and continually improving a service management system. An SMS supports the management of the service lifecycle, including the planning, design, transition, delivery and improvement of services, which meet agreed requirements and deliver value for customers, users and the organization delivering the services.". The 2018 version (ISO/IEC 20000-1:2018) comprises ten sections, following the high-level structure from Annex SL of the Consolidated ISO/IEC Directives, Part 1:
ISO/IEC 20000-3:2019 provides guidance on scope definition, applicability and demonstration of conformance for service providers aiming to meet the requirements of ISO/IEC 20000-1, or for service providers who are planning service improvements and intending to use ISO/IEC 20000 as a business goal. It supplements the advice in ISO/IEC 20000-2, which provides generic guidelines for implementing an SMS in accordance with ISO/IEC 20000-1.
As with most ISO standards, organizations and individuals seek training towards establishing knowledge and excellence in applying the standard. The certification scheme targets organizations, while the qualification scheme targets individuals.
In terms of certification, there are leading certification bodies around the world, for instance, BSI in UK, Quality Austria in Austria, JQA in Japan, KFQ in Korea and SAI Global in Australia, Asia and Americas.
The importance of certification to ISO/IEC 20000 is not correlated by global adoption.[5] ISO collects the number of certificates issued from the different certification bodies and publishes the results annually in The ISO Survey of Management System Standard Certifications. The 2020 survey reports that 7846 (5461 in China) certificates were issued for ISO/IEC 20000.[6]
PowerJack via eBay auction>>>> last night I scored a 20k AMG version PowerJack PSW SP LF inverter it is a 48 volt unit so i will have to put 2 of my 24-volt tech direct prefab batteries together to get a 48 volt battery to test it on.
Like to know if the transformer is 32vac ASL6.5 or ASL9.0 which would be better for lithium IRON phosphate battery 56 volts . The control board should be rev 11.1 . Like to know if the LED on the LF driver always stay OFF . Thank you .
I've had this on both of the 8kW (claimed) mainboards that I have had in the past year - one 10.3 and one 11.1, and I notice the same on your mainboard. I have added the 4th cap myself on both boards as they don't cost much and my assumption is that 4 caps are better than 3! Nothing untoward has happened yet despite several months of use.
However I do agree the old ones are better - my old 2013 PJ 8k is still the best performer and doesn't have any heat problems since I replaced the aged unbranded fan with a Delta 24V 1.5A one last year. I just don't use the old one over winter as the high idle current of the twin transformers wastes too much of the precious little solar power that we get Oct-Feb.
Can't argue with that! The older large mainboards had 6 caps, then they started only putting in 5 of 6. Then they changed to the small boards with 4 spots and almost immediately only filled 3 of 4. Maybe 3 is "enough" but I feel better with 6.
Comes down to acceptable levels of AC load induced ripple and droop under abrupt load increases. Lots of ripple is not good for the longevity of the battery (LA, li, what ever type you like). Yes, they might be using capacitors with high capacitance and better ripple current ratings to counter the lower number... but I seriously doubt that ?
They had a spate of bad caps recently (the black ones, not the brown/purple ones they're using now)...must have been cheaper, but they ended up with a rash of capacitor failures causing FETs to blow out--yeah, it was colorful. Caps would leak electrolyte / corrode off their own leads, etc. It was bad enough that they went back to the purple ones.
Thankfully all three mainboards (the v1.4, 10.3 and 11.1) that I have are all fitted with the same brand of 'brown' capacitors. Not seen any purple ones. The ancient v1.4 had 4, but the newer two were only fitted with 3 out of 4. I wasn't able to find a source of the brown so the ones I bought for infill of the missing caps were these:
They look different to the photo's of the ones I have seen on blown PJ boards so hopefully will last, especially as there there are three of the 'good' ones already on each mainboard. But I bought 4 so I have a couple of spare ones. Been running the house and garage during daytime and evening on the v10.3 for nearly 3 months now with some fairly heavy loads on a daily basis. checked this morning and the new cap still looks ok (no obvious leakage).

I added 6 more capacitor outside of the inverter for a total of 12 capacitors and no problem running for a month now with the rev 11.1 control board . 12 capacitors help start inductive load like microwave oven and 5hp air compresser .
still have not opened it (the 20K AMG version inverter) but got more solar panels mounted on the array structures (unistrut and 2x6 wood triangles at 45 degrees fixed ground mounts with some concrete blocks to level them), and 28 of 32 LiFePO4 Eve cells LF280K have arrived along with some other battery necessities. going toadd more ballast but not much problems although the wind has taken one and added a dent to it before i got it mounted. Thirty 250-watt PV panels mounted now>>>> a feat for this old one man operation.
So long as the voltage rating is higher than expected peak voltage input by a safe margin it shouldn't be a problem. The large increase in capacitance may present a problem for the PCB if the inverter is ever dead dropped onto a battery etc without precharging, depending on the track width and copper thickness. Fuses / breakers may need to be uprated likewise. Of course it should never be done but its the things that are never done that always get you.
With the update of the standard, new requirements have been introduced in ISO 20000:2018 (for example in the areas of service planning and delivery), some content has been removed (such as references to the 'PDCA' methodology), and several clauses have been rephrased in the latest edition of ISO 20000 to be more generic.
Part 1 of ISO/IEC 20000 (ISO/IEC 20000-1) specifies requirements for "establishing, implementing, maintaining and continually improving a service management system (SMS)". These are the mandatory requirements which must be fulfilled by organizations to be compliant with the ISO 20000 standard.
The first three sections of ISO 20000:2018, Part 1 do not contain requirements which must be fulfilled. Section 1 outlines the standard's intended use and applicability. Section 2 lists normative references (no normative references are cited at this point in time). Section 3 contains terms and definitions.
Following the release of ISO 20000:2018, organizations will have to transition their certificates to the latest 2018 edition of the standard. The International Accreditation Forum (IAF) has set the following transition periods and rules:
Please note: These transition periods and rules have been set by the International Accreditation Forum (IAF). National accreditation bodies may choose to set slightly different rules - please consult your auditor to find out the precise rules applicable to your organization.
