The GWL/Modular Solution in Action
One of the main advantages of theGWL/Modular solution is that it comes with a complete set of documentation. The goal of this concept is that the product is fully replicable and serviceable at any location of the world by the local skilled electricians.
This is the difference between the Modular –
Details of the Emergency Output for CPM1
Pin # 1 - Main Turn-on Impulse- 150 ms pulse to GND
The pin will be connected to GND for 150 ms when the board is powered on, or after the board has been reset (and restarted).
This pin is designed to give an impulse to the bistable relay or to give a power-on impulse to the auxiliary controls
The CPM1 Emergency Voltage Levels
The Emergency Voltage levels [U Emergency] are 0.3V bellow theUminand 0.3V above theUmaxlevels. They become active if the voltage of any cells reaches these levels for 30 seconds.
U Emergency (Min)
LFP: 2.5V, 2.6V, 2.7V, 2.8V
LTO: 1.4V, 1.5V, 1.6V, 1.7V
U Emergency (Max)
LF
Dogma: The energy of the regular “AA” cells = 1.43Wh
The AA cells are the primary one-time use cells. The nominal voltage ofthe AA cells is 1.5Vand their capacity in Ah usually not stated in the specification.It shows that people are fooled easily. ????

Integration of the GWL/Modular with Victron Energy products
The reference of theshows the possibility of the integration of the GWL/Modular components with theVictron Energy products.
In this installation the CPM1 communicates (by means of auxiliary relays) with theAUX1 and AUX2 of Victron Multiplus, and the

GWL/Modular – CPM1 - Auxiliary Relays for High Power...
As seen from the demonstration designs provided by GWL and also from the manual of the, the high-power outputs need to be connected by means of the auxiliary relays.
The auxiliary relaysprovide another layer of protection and disconnectionbetween the battery pack e

Avoiding petty risks with home storage
Perhaps a small neglection of the maintenance of an airplane can cause the whole plane to crash. Also, a small negligence can cause somerisky situations concerning the energy storage solution.
