General / solar storage uk

Last post by carltovey - February 10, 2024, 06:40:35 PM

I would like to add either a retrofit inverter and batteries that monitors grid usage and then charges batteries when house load is fulfilled then discharge back to house loads when solar is down, I do not have tariff to charge battery from grid ,I need a grid tie system I have a 3kw at rear of garden on shed and 3 other small systems about 1.5kw each

Or i could change my 3kw growatt grid tie inverter at bottom of garden to one that is grid tied and will charge batteries.
Can anyone recommend a system, as there are that many inverters and batteries out there that a recommendation from someone that has already got a working system, Must be able to set inverter to not charge batteries from grid.

Last post by freeflow - December 10, 2023, 04:36:07 PM

Hi
Can somebody tell me if a standard heat source pump installation uses a pressurized hot water tank? Or will the pressure for the hot water be the same as with my oil boiler and water storage tank (gravity-fed)?

General Discussion / Funding/investment/partnership...

Last post by RevI - December 09, 2023, 03:43:16 PM

I am an Indian inventor. For a long time, I am continuing personal research about a new kind of wind power generation system. Recently, while searching net, I have found out that the necessary machinery is already available in market. In short, the machine now can be built easily.
At present, I have completed the CAD drawing and done some ANSYS simulation testing. As per the latest simulation where the RPM was set of 3600, the torque was found to be around 1.52 Newton-meter for a machine of 35 cm diameter and the input wind velocity was set to be 6 m/s. For me, this is promising result and I can say that no wind turbine in anywhere around the world of that little diameter can generate such torque at this RPM.
I am looking for partnership/investment/funding for further development and commercialization of the technology
